| 1 | Temperature dependence of the point defect properties of GaN thin films studied by terahertz time-domain spectroscopy显示文摘The dielectric functions of GaN for the temperature and frequency ranges of 10–300 K and 0.3–1 THz are obtained using terahertz time-domain spectroscopy.It is found that there are oscillations of the dielectric functions at various temperatures.Physically,the oscillation behavior is attributed to the resonance states of the point defects in the material.Furthermore,the dielectric functions are well fitted by the combination of the simple Drude model together with the classical damped oscillator model.According to the values of the fitting parameters,the concentration and electron lifetime of the point defects for various temperatures are determined,and the temperature dependences of them are in accordance with the previously reported result.Therefore,terahertz time-domain spectroscopy can be considered as a promising technique for investigating the relevant characteristics of the point defects in semiconductor materials. | FANG HeNan ZHANG Rong LIU Bin LI YeCao FU DeYi LI Yi XIE ZiLi ZHUANG Zhe ZHENG YouDou WU JingBo JIN BiaoBing CHEN Jian WU PeiHeng | 2013 | Science China(Physics,Mechanics & Astronomy)2013，56，11： | 6 |

| 5 | Origin mechanism of pitting corrosion induced by cerium inclusions显示文摘In this paper,the origin mechanism of pitting corrosion induced by Ce_(2)O_(3),Ce_(2)O_(2)S,and CeAlO_(3) inclusions in a microalloyed steel was investigated by field emission scanning electron microscopy with energy dispersive spectroscopy and electron backscattered diffraction,conductivity atomic force microscopy,immersion test,and first-principles calculation.The results show that the Ce_(2)O_(3),Ce_(2)O_(2)S,and CeAlO_(3) inclusions are non-conductive,which are impossible to form corrosion couples with the steel matrix.There are no obvious lattice distortion zones in the steel matrix around the Ce_(2)O_(3),Ce_(2)O_(2)S,and CeAlO_(3) inclusions,so it is difficult to form micro-galvanic corrosion near the Ce inclusion.The order of work functions of the Ce inclusions and the steel matrix from small to large is Ce_(2)O_(2)S | Xiangjun Liu Changqiao Yang Huiping Ren Yiming Li Zili Jin Fang Zhang Jichun Yang | 2023 | Journal of Rare Earths2023，41，9： | 0 |
| 6 | Improving iconic memory through contrast detection training with HOA-corrected vision显示文摘Iconic memory and short-term memory are not only crucial for perception and cognition,but also of great importance to mental health.Here,we first showed that both types of memory could be improved by improving limiting processes in visual processing through perceptual learning.Normal adults were trained in a contrast detection task for ten days,with their higher-order aberrations(HOA)corrected in real-time.We found that the training improved not only their contrast sensitivity function(CSF),but also their iconic memory and baseline information maintenance for short-term memory,and the relationship between memory and CSF improvements could be well-predicted by an observer model.These results suggest that training the limiting component of a cognitive task with visual perceptual learning could improve visual cognition.They may also provide an empirical foundation for new therapies to treat people with poor sensory memory. | Ling Gong Junlei Zhao Yun Dai Zili Wang Fang Hou Yudong Zhang Zhong-Lin Lu Jiawei Zhou | 2024 | Fundamental Research2024，4，1： | 0 |
