and an annealing under N2 atmosphere at 500 ℃ for 60 min. Under a bias voltage of 100 V, the net photocurrent is obtained under 55Fe(5.9 keV) X-rays and 241Am (5.5 MeV) a particles radiation, respectively. The photocurrent increases rapidly at first and becomes stable for the "pumping" effect with the radiation time. Key words: diamond film; hot filament chemical vapor deposition(HFCVD); annealing......
Au与p-CZT接触的界面势垒研究 介万奇1,李强1,查钢强1,傅莉1 (1.西北工业大学,材料科学与工程学院,陕西,西安,710072) 摘要:用同步光电子能谱研究了NH4F/H2O2钝化p-CZT表面效应, 钝化处理晶体表面后,表面态能峰消失.用未钝化和钝化两种工艺方法来对比p-CZT晶体表面的钝化效果.同时用同步光电子能谱研究了Au与p-CZT接触的界面势垒.其中界面势垒可以由价带区域的新能级EV-C 和新能级与Fermi能级的差决定.未钝化和钝化的Au/p-CZT的界面势垒分别为(0.88±0.1)eV和(1.17±0.1)eV. 关键词:同步光电子能谱; 界面势垒; 钝化; synchrotron photoemission spectroscopy (SRPES); interface barrier; passivation; [全文内容正在添加中] ......
