引言硒砷碲摄象管(Saticon)是一种具有分辨率高,暗电流小,惰性小等优良特性的光导摄象管,它的各项技术指标都已达到氧化铝管的水平,已广泛用于彩色广播电视摄象系统。硒砷碲摄象管靶面是由无定型硒(Se)做主体材料而掺以一定比例的砷(As)、碲(Te)、而组成的。掺 As 的目的是增加无定型 Se 材料的热稳定性。由实验研究已证明,在无定型 Se 中均匀掺以7—15%原子比的 As 可得到即热稳定性好,又保持无定型 Se 良好光电特性的靶面、掺 Te 的目的是改善靶面的光谱响应。实验已表明纯 Se 或掺 As10—15%的 Se
Introduction The selenium, arsenic and tellurium phototool (Saticon) is a kind of photoconductive phototool possessing high resolution, low dark current, small inertness and other excellent characteristics. Its technical indicators have reached the level of the alumina tube and has been widely used For color broadcast television camera system. Selenium arsenic tellurium phototool target surface is made of amorphous selenium (Se) as the host material doped with a certain percentage of arsenic (As), tellurium (Te), and composition. The purpose of doping As is to increase the thermal stability of amorphous Se materials. Experimental studies have shown that uniformly doped with As in amorphous 7 to 7 atomic% of As can get good thermal stability, but also to maintain a good photoelectric properties of amorphous Se target surface, the purpose of Te is to improve the target surface Spectral response. Experiments have shown that pure Se or doped As10-15% of Se
