1High-voltage 4H-SiC PiN diodes with the etched implant junction termination extension显示文摘This paper presents the design and fabrication of an etched implant junction termination extension(JTE)for high-voltage 4H-SiC PiN diodes. Unlike the conventional JTE structure, the proposed structure utilizes multiple etching steps to achieve the optimum JTE concentration range. The simulation results show that the etched implant JTE method can improve the blocking voltage of SiC PiN diodes and also provides broad process latitude for parameter variations, such as implantation dose and activation annealing condition. The fabricated SiC PiN diodes with the etched implant JTE exhibit a highest blocking voltage of 4.5 kV and the forward on-state voltage of 4.6 V at room temperature. These results are of interest for understanding the etched implant method in the fabrication of high-voltage power devices.Juntao Li Chengquan Xiao Xingliang Xu Gang Dai Lin Zhang Yang Zhou An Xiang Yingkun Yang Jian Zhang 2017Journal of Semiconductors2017,38,2:2
2Highly-efficient thermoelectric-driven light-emitting diodes based on colloidal quantum dots显示文摘Driven by sub-bandgap electric work and Peltier heat,thermoelectric-driven light-emitting diodes(TED-LEDs)not only offer much enhanced power-conversion-efficiency but also eliminate the waste heat generated during the operation of LEDs.However,costeffective and high-efficiency TED-LEDs are not readily accessible for the epitaxially grown III-V LEDs due to the high chip cost and efficiency droop at low-medium brightness(current densities).Here we show that electroluminescence of colloidal quantum dots(QDs)LEDs(QLEDs)circumvents the deficiencies faced by conventional LEDs.The optimal red-emitting device fabricated by cost-effective solution processing technics exhibits external-and internal-power-conversion-efficiency of 21.5%and 93.5%at 100 cd/m^(2),suited for high-efficiency solid-state lighting and high-resolution display.At this brightness,the electric driving voltage(V)of 1.89 V is lower than the photon voltage(Vp=hv/q=1.96 V,q being the elemental charge).With typical Vp=1.96 V,electroluminescence can be detected with the driving voltage as low as 1.0-1.2 V.Luminance of the thermoelectric-driven QLEDs(TED-QLEDs)remains ideally diffusion-dominated with the driving voltage lower than~1.5 V,and further improvement on charge transport is expected to extend the linear ideality to all practical driving voltages.Xing Lin Xingliang Dai Zikang Ye Yufei Shu Zixuan Song Xiaogang Peng 2022Nano Research2022,15,10:2

5Ligand Exchange of Colloidal ZnO Nanocrystals from the High Temperature and Nonaqueous Approach显示文摘Colloidal zinc oxide(ZnO) nanocrystals generated from the high temperature and nonaqueous approache are attractive for use in solution-processed electrical and optoelectronic devices. However, the asprepared colloidal ZnO nanocrystals by this approach are generally capped by ligands with long alkyl-chains,which is disadvantage for solution-processed devices due to hindering charge transport. Here we demonstrate an effective ligand exchange process for the colloidal ZnO nanocrystals from the high temperature and nonaqueous approach by using n-butylamine. The ligand exchange process was carefully characterized. The thin films based on colloidal ZnO nanocrystals after ligand exchange exhibited dramatically enhanced UV photoconductivity.Jun Luo Xingliang Dai Sai Bai Yizheng Jin Zhizhen Ye Xiao jun Guo 2013Nano-Micro Letters2013,5,4:1
6Ultrastable and highly efficient CsPbBr_(3) composites achieved by dual-matrix encapsulation for display devices显示文摘Perovskite nanocrystals(NCs)with high stabilities and excellent optical perfor-mances are crucial for display applications.However,to date,perovskite emitters with both high photoluminescence(PL)quantum yield(PLQY)and high stabili-ties under harsh synergistic humidity–heat–light aging conditions have not been reported.The promising high-temperature solid-state sintering with single oxide matrices cannot ensure high PLQY and synergistic aging stabilities of perovskites.Herein,both the PLQY and overall(thermal,moisture,and photo)stabilities of all-inorganic perovskite(CsPbBr_(3))NCs are improved by dual-matrix encapsula-tion,which is accomplished by in situ crystallization of CsPbBr_(3)@Cs_(4)PbBr_(6)nanocomposites in silica molecular sieve(MS)templates via advanced solid-state synthesis a using precisely controlled molar ratio of precursor components and cooling rates.The Cs_(4)PbBr_(6)matrix effectively passivates the surfaces of CsPbBr_(3)NCs,and the MS matrix insulates CsPbBr_(3)@Cs_(4)PbBr_(6)from the external environ-ment.The resulting CsPbBr_(3)@Cs_(4)PbBr_(6)/MS composites exhibit the highest PLQY(>90%)among those of the solid-state perovskite NCs and significant stabilities against water,heat,and blue light irradiation,maintaining more than 80%of their initial PL intensities after being aged for 1000 h under synergistic high-humidity(85%),high-temperature(85C),and strong blue light irradiation(350 mW cm2)conditions.To the best of our knowledge,these CsPbBr_(3)@Cs_(4)PbBr_(6)/MS composites represent the most stable perovskite emitters under synergistic humidity–heat–light aging conditions.The liquid crystal display backlight module fabricated using these stable composites demonstrates a wide color gamut of 131%of the National Television Standards Committee standard.We speculate that this dual-matrix encapsulation can be used for industrial mass production.Chao Fan Haipeng Liu Jianwu Zhou Xingliang Dai Haiping He Zhizhen Ye 2023InfoMat2023,5,7:0
7Preliminary analysis of cellular sociology of co-cultured glioma initiating cells and macrophages in vitro显示文摘Objective: Real-time monitoring of cytokine secretion at the single immunocyte level,based on the concept of immune cells, sociology has been recently reported. However,the relationships between glioma-initiating cells(GICs) and host immune cells and their mutual interactions in the tumor microenvironment have not been directly observed and remain unclear. Methods: The dual fluorescence tracing technique was applied to label the co-cultured GICs and host macrophages(M?), and the interactions between the two types of cells were observed using a live cell imaging system. Fusion cells in the co-culture system were monocloned and proliferated in vitro and their social interactions were observed and recorded. Results: Using real-time dynamic observation of target cells, 6 types of intercellular conjunction microtubes were found to function in the transfer of intercellular information between GICs and M?; GICs and host M? can fuse into hybrid cells after several rounds of mutual interactions, and then these fusion cells fused with each other; Fusion cells generated offspring cells through symmetrical and asymmetrical division or underwent apoptosis. A 'cell in cell' phenomenon was observed in the fusion cells, which was often followed by cell release, namely entosis. Conclusions: Preliminary studies revealed the patterns of cell conjunction via microtubes between GICs and host M? and the processes of cell fusion, division, and entosis. The results revealed malignant transformation of host M?, induced by GICs, suggesting complex social relationships among tumor-immune cells in gliomas.Mingxia Zhang Junjie Chen Lin Wang Xiaoyan Ji Lin Yang Yujing Sheng Hairui Liu Haiyang Wang Aidong Wang Xingliang Dai Xiaonan Li Qiang Huang Jun Dong 2016Translational Neuroscience and Clinics2016,2,2:0
8MAGED4B Promotes Glioma Progression via Inactivation of the TNF-α-induced Apoptotic Pathway by Down-regulating TRIM27 Expression显示文摘MAGED4B belongs to the melanoma-associated antigen family;originally found in melanoma,it is expressed in various types of cancer,and is especially enriched in glioblastoma.However,the functional role and molecular mechanisms of MAGED4B in glioma are still unclear.In this study,we found that the MAGED4B level was higher in glioma tissue than that in non-cancer tissue,and the level was positively correlated with glioma grade,tumor diameter,Ki-67 level,and patient age.The patients with higher levels had a worse prognosis than those with lower MAGED4B levels.In glioma cells,MAGED4B overexpression promoted proliferation,invasion,and migration,as well as decreasing apoptosis and the chemosensitivity to cisplatin and temozolomide.On the contrary,MAGED4B knockdown in glioma cells inhibited proliferation,invasion,and migration,as well as increasing apoptosis and the chemosensitivity to cisplatin and temozolomide.MAGED4B knockdown also inhibited the growth of gliomas implanted into the rat brain.The interaction between MAGED4B and tripartite motif-containing 27(TRIM27)in glioma cells was detected by co-immunoprecipitation assay,which showed that MAGED4B was co-localized with TRIM27.In addition,MAGED4B overexpression down-regulated the TRIM27 protein level,and this was blocked by carbobenzoxyl-L-leucyl-L-leucyl-L-leucine(MG132),an inhibitor of the proteasome.On the contrary,MAGED4B knockdown up-regulated the TRIM27 level.Furthermore,MAGED4B overexpression increased TRIM27 ubiquitination in the presence of MG132.Accordingly,MAGED4B down-regulated the protein levels of genes downstream of ubiquitin-specific protease 7(USP7)involved in the tumor necrosis factor-alpha(TNF-α)-induced apoptotic pathway.These findings indicate that MAGED4B promotes glioma growth via a TRIM27/USP7/receptor-interacting serine/threonine-protein kinase 1(RIP1)-dependent TNF-α-induced apoptotic pathway,which suggests that MAGED4B is a potential target for glioma diagnosis and treatment.Can Liu Jun Liu Juntang Shao Cheng Huang Xingliang Dai Yujun Shen Weishu Hou Yuxian Shen Yongqiang Yu 2023Neuroscience Bulletin2023,39,2:0
9A 3D Nonhydrostatic Compressible Atmospheric Dynamic Core by Multi-moment Constrained Finite Volume Method显示文摘A 3D compressible nonhydrostatic dynamic core based on a three-point multi-moment constrained finite-volume (MCV) method is developed by extending the previous 2D nonhydrostatic atmospheric dynamics to 3D on a terrainfollowing grid. The MCV algorithm defines two types of moments: the point-wise value (PV) and the volume-integrated average (VIA). The unknowns (PV values) are defined at the solution points within each cell and are updated through the time evolution formulations derived from the governing equations. Rigorous numerical conservation is ensured by a constraint on the VIA moment through the flux form formulation. The 3D atmospheric dynamic core reported in this paper is based on a three-point MCV method and has some advantages in comparison with other existing methods, such as uniform third-order accuracy, a compact stencil, and algorithmic simplicity. To check the performance of the 3D nonhydrostatic dynamic core, various benchmark test cases are performed. All the numerical results show that the present dynamic core is very competitive when compared to other existing advanced models, and thus lays the foundation for further developing global atmospheric models in the near future.Qingchang QIN Xueshun SHEN Chungang CHEN Feng XIAO Yongjiu DAI Xingliang LI 2019Advances in Atmospheric Sciences2019,36,10:0
10Highly spectra-stable pure blue perovskite light-emitting diodes based on copper and potassium co-doped quantum dots显示文摘Halide perovskite light emitting diodes(LEDs)have gained great progress in recent years.However,mixed-halide perovskites for blue LEDs usually suffer from electroluminescence(EL)spectra shift at a high applied voltage or current density,limiting their efficiency.In this work,we report a strategy of using single-layer perovskite quantum dots(QDs)film to tackle the electroluminescence spectra shift in pure-blue perovskite LEDs and improve the LED efficiency by co-doping copper and potassium in the mixed-halide perovskite QDs.As a result,we obtained pure-blue halide perovskite QD-LEDs with stable EL spectra centred at 469 nm even at a current density of 1,617 mA·cm^(−2).The optimal device presents a maximum external quantum efficiency(EQE)of 2.0%.The average maximum EQE and luminance of the LEDs are 1.49%and 393 cd·m^(−2),increasing 62%and 66%compared with the control LEDs.Our study provides an effective strategy for achieving spectra-stable and highly efficient pure-blue perovskite LEDs.Fang Chen Wenjie Ming Yongfei Li Yun Gao Lea Pasquale Kexin Yao Boyuan Huang Qiuting Cai Guochao Lu Jizhong Song Mirko Prato Xingliang Dai Haiping He Zhizhen Ye 2023Nano Research2023,16,5:0
