| 1 | Patterned growth ofβ-Ga_(2)O_(3) thin films for solar-blind deep-ultraviolet photodetectors array and optical imaging application显示文摘Solar-blind deep-ultraviolet(DUV)photodetectors based on Ga_(2)O_(3)have attracted great attention due to their potential applications for many military and civil purposes.However,the development of device integration for optoelectronic system applications remains a huge challenge.Herein,we report a facile method for patterned-growth of high-qualityβ-Ga_(2)O_(3)thin films,which are assembled into a photodetectors array comprising 8×8 device units.A representative detector exhibits outstanding photoresponse performance,in terms of an ultra-low dark current of 0.62 pA,a large Ilight/Idark ratio exceeding 10^(4),a high responsivity of 0.72 A W^(-1) and a decent specific detectivity of 4.18×10^(11)Jones,upon 265 nm DUV illumination.What is more,the DUV/visible(250/400 nm)rejection ratio is as high as 10^(3) with a sharp response cut-off wave length at 280 nm.Further optoelectronic analysis reveals that the photodetectors array has good uniformity and repeatability,endowing it the capability to serve as a reliable DUV light image sensor with a decent spatial resolution.These results suggest that the proposed technique offers an effective avenue for patterned growth ofβ-Ga_(2)O_(3)thin films for multifunctional DUV optoelectronic applications. | Chao Xie Xingtong Lu Yi Liang Huahan Chen Li Wang Chunyan Wu Di Wu Wenhua Yang Linbao Luo | 2021 | Journal of Materials Science & Technology2021，，13： | 7 |
| 2 | Hybrid nano-scale Au with ITO structure for a high-performance near-infrared silicon-based photodetector with ultralow dark current显示文摘An internal photoemission-based silicon photodetector detects light below the silicon bandgap at room temperature and can exhibit spectrally broad behavior,making it potentially suited to meet the need for a near-infrared pure Si photodetector.In this work,the implementation of a thin Au insertion layer into an ITO/n-Si Schottky photodetector can profoundly affect the barrier height and significantly improve the device performance.By fabricating a nanoscale thin Au layer and an ITO electrode on a silicon substrate,we achieve a well-behaved ITO/Au/n-Si Schottky diode with a record dark current density of 3.7×10^(−7) A/cm^(2) at−1 V and a high rectification ratio of 1.5×10^(8) at±1 V.Furthermore,the responsivity has been obviously improved without sacrificing the dark current performance of the device by decreasing the Au thickness.Such a silicon-based photodetector with an enhanced performance could be a promising strategy for the realization of a monolithic integrated pure silicon photodetector in optical communication. | Xinxin Li Zhen Deng Jun Li Yangfeng Li Linbao Guo Yang Jiang Ziguang Ma Lu Wang Chunhua Du Ying Wang Qingbo Meng Haiqiang Jia Wenxin Wang Wuming Liu Hong Chen | 2020 | Photonics Research2020，8，11： | 4 |
| 3 | An animal model of cerebral palsy induced by prenatal exposure to lipopolysaccharide and hypoxia显示文摘BACKGROUND:Neonatal cerebral palsy is mainly caused by prenatal factors.At present, an animal model of prenatal infection and early postnatal hypoxia does not exist.OBJECTIVE:To observe morphology and motor performance following prenatal infection and hypoxic insult-induced brain damage of neonatal rats to verify the feasibility to establish a model of cerebral palsy.DESIGN, TIME AND SETTING:A randomized, controlled, animal experiment was performed at the Laboratories of Xinjiang Center for Disease Control and Prevention from September 2007 to June 2008.MATERIALS:The hypoxic incubator was purchased from Shanghai Pediatric Medical Institute, China.Lipopolysaccharide (LPS, Escherichia coli, O55:B5) was purchased from Sigma-Aldrich (St.Louis, MO, USA).METHODS:A total of 27 Wistar rats, aged 7 days, were randomly assigned to sham-surgery group (n=15) with no carotid artery incision or hypoxia treatment, hypoxia/ischemia (H/I) group (n=12) undergoing ligature of the right common carotid artery followed by exposure to hypoxia at postnatal day 7 (P7), and LPS/H group (n=19), in which pregnant rats were exposed in utero to LPS followed by prenatal hypoxia at embryonic day 16.MAIN OUTCOME MEASURES:Behavior, compound muscle action potential, and pathological changes were observed in 28-day-old rats.RESULTS:The footprint repeat space showed that left limb footprint repeatability in the H/I and LPS/H groups was lower than in the sham-surgery group (P<0.05).The space between the footprints was larger and unstable.Hind limb quadricep compound muscle action potential in the H/I and LPS/H groups showed lower wave amplitude compared with the sham-surgery group (P<0.05).Hematoxylin and eosin staining showed irregular cells around the ventricle, as well as periventricular leukomalacia.CONCLUSION:An animal model of cerebral palsy was established, which simulated the human condition most likely associated with occurrence of this disease.This model could be used for experimental studies related to cerebral palsy. | Gang Chen Yanrong HU Wei Liu Jiang Li Linbao Wen Jianxin Li Lihui Zhao Xiaopeng Yang Yi Zhu Zhenzhu Sun Guangming Chi | 2010 | Neural Regeneration Research2010，5，14： | 4 |
