| 1 | 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 | Comparison of the Educational Effect upon Myopia Prevention and Treatment between Video Demonstration and Traditional Teaching显示文摘Purpose:.To compare the education effect of video demonstrations and conventional teaching on the prevention and control of myopia.Methods:.Eighty students were randomly divided into an experimental(n=40) and a control(n=40) group,.and each group was split into two classes of 40 students..The students in the experimental group attended classes mainly based on video demonstration and those in the control group received conventional teaching..All students then undertook a test and the examination scores were statistically compared between the two groups.Results:.The educational background,.age,.and gender did not differ between the two groups(all P >0.05). The experimental group had a mean test score of 8.25±1.45,.which was slightly lower than the mean of 8.58±1.11 in the control group,but the difference was not statistically significant(t=-1.589,P=0.114).Conclusion:.The educational effect of video demonstrations was almost identical to that of traditional teaching..In addition,.video classes reduced the training time and financial costs,.indicating that they deserve widespread application. | Yunkai Lu Yangfeng Guo Hongxing Diao Xiaosong Liang Jinhua Lu Yangfa Zeng | 2015 | Eye Science2015，30，2： | 0 |
