| 1 | Analysis of TM/TE mode enhancement and droop reduction by a nanoporous n-AIGaN underlayer in a 290 nm UV-LED显示文摘A full structure 290 nm ultraviolet light emitting diode(UV-LED)with a nanoporous n-AlGaN underlayer was fabricated by top via hole formation followed by high-voltage electrochemical etching.The 20 to 120 nm nanopores were prepared in regular doped n-AlGaN by adjusting the etching voltage.The comparison between the Raman spectrum and the photoluminescence wavelength shows that the biaxial stress in the nanoporous material is obviously relaxed.The photoluminescence enhancement was found to be highly dependent on the size of the pores.It not only improves the extraction efficiency of top-emitting transverse-electric(TE)-mode photons but also greatly improves the efficiency of side emitting tran sverse-magnetic(TM)-mode photons.This leads to the polarization change of the side-emitting light from-0.08 to-0.242.The intensity of the electroluminescence was increased by 36.5%at 100 mA,and the efficiency droop at high current was found to decrease from 61%to 31%. | YUFENG LI CHENYU WANG YE ZHANG PENG HU SHENGNAN ZHANG MENGQI DU XILIN SU QIANG LI FENG YUN | 2020 | Photonics Research2020，8，6： | 2 |

| 6 | Associations of insulin resistance and beta-cell function with abnormal lipid profile in newly diagnosed diabetes显示文摘Background:Abnormal lipids are strong predictors of cardiovascular disease in type 1 diabetes mellitus(T1DM)and type 2 diabetes mellitus(T2DM).However,the potential associations of insulin resistance(IR)and beta-cell function(BCF)with abnormal lipids in newly diagnosed T1DM or T2DM patients are not fully understood.Methods:A cross-sectional survey of 15,928 participants was conducted.Homeostasis model assessment and postprandial C-peptide levels were used to estimate IR and BCF.A restricted cubic spline(RCS)nested in binary logistic regression was used to examine the associations of IR and BCF with abnormal lipids.Results:High triglyceride(TG),low high-density lipoprotein cholesterol,and high low-density lipoprotein cholesterol(LDL-C)accounted for 49.7%,47.8%,and 59.2%of the participants,respectively.In multivariable analysis,high IR was associated with an increased risk of high TGs(P for trend<0.001)in T1DM and is associated with an elevated risk of high TG and low HDL-C(all P for trend<0.01)in T2DM.Low BCF was not associated with risks of dyslipidemia in patients with T1DM or T2DM after adjustment for potential confounders.Conclusion:High IR had different associations with the risk of dyslipidemia in newly diagnosed T1DM and T2DM patients,suggesting that early treatment that improves IR may benefit abnormal lipid metabolism. | Xiaohan Tang Xiang Yan Houde Zhou Gan Huang Xiaohong Niu Hongwei Jiang Heng Su Xilin Yang Xia Li Zhiguang Zhou | 2022 | Chinese Medical Journal2022，135，21： | 1 |

| 10 | Phosphor-free microLEDs with ultrafast and broadband features for visible light communications显示文摘Modulation bandwidth and the emission region are essential features for the widespread use of visible light communications(VLC).This paper addresses the contradictory requirements to achieve broadband and proposes ultrafast,asymmetric pyramids grown on adjacent deep concave holes via lateral overgrowth.Multicolor emission with an emission region between 420 nm and 600 nm is obtained by controlling the growth rate at different positions on the same face,which also can provide multiple subcarrier frequency points for the employment of wavelength division multiplexing technology.The spontaneous emission rate distinction is narrowed by lowering the number of the crystal plane,ensuring a high modulation bandwidth over broadband.More importantly,the residual stress and dislocation density were minimized by employing a patterned substrate,and lateral overgrowth resulted in a further enhancement of the recombination rate.Finally,the total modulation bandwidth of multiple subcarriers of the asymmetric pyramids is beyond GHz.These ultrafast,multicolor microLEDs are viable for application in VLC systems and may also enable applications for intelligent lighting and display. | Zhenhuan Tian Qiang Li Xuzheng Wang Mingyin Zhang Xilin Su Ye Zhang Yufeng Li Feng Yun S.W.Ricky Lee | 2021 | Photonics Research2021，9，4： | 0 |
