Since the discovery of Ag-O-Cs photocathode, its mechanism of photoemission has remained enigmatic. The role of silver colloidal particles is important for the explana-tion of photoemission in long wavelength region. This paper presents a general review of the role of silver colloidal particles in the literatures, such as experiments by Лахомов et al. We come to a conclusion that the photoelectric emission of Ag-O-Cs photocathode above 4000A comes from small silver colloidal particles in the film of Cs2O.

银氧铯阴极中银胶粒的作用是讨论此种阴极长波光电发射机理的关键。本文对文献中出现的对这种阴极中银胶粒的性质和作用的观点进行了分析和评述。评述是在“它的长波光电发射来自固溶小银胶粒”的观点上进行的,并认为这个观点是合理的。 本文对等人的实验作了介绍,并指出烘烤后红外灵敏度的增加是由于该阴极中因加热扩散而增加了小银胶粒,因为在固溶胶体系中用扩散办法来增加杂质原子浓度并不能使施主原子浓度增加(假定激活烘烤温度不变)。 本文还对这种阴极的红外光吸收和红外光电发射之间的关系进行了讨论。

Using (20-300K) Hall coefficient measurement and (6-300K) IR optical absorption, thermal donor generated in P-CZ Si single crystal after heat treatment at 450℃ over a wide range of time has been studied. It is shown from Hall coefficient measurements that two donor levels in the specimen after 100 hrs. annealing are observed: E1 = 56 meV, E2 = 110 meV. Low temperature IR optical absorption of specimens after annealing of different duration shows complex structure arising from thermal donor. The intensity and number of the absorption peaks increase with increasing duration of annealing. The results obtained can be phenomenologically explained fairly well by the hydrogen-like effective mass approximation theroy assuming the occurence of different species of doubly charged donor. The oxygen-related thermal donor can also be possibly understood as doubly charged donor. The number of species of thermal donor is closely correlated to the duration of annealing.

利用20—300K的Hall系数测量和6-300K的红外光吸收,研究了含氧P型CZ硅单晶经450℃不同时间热处理后所产生的热施主问题。Hall系数测量表明:经100hr热处理的样品存在两个施主能级:E_1=58meV,E_2=110meV。对不同热处理时间的样品,从低温红外光吸收则可看见由于热施主所引起的复杂吸收光谱。这些吸收峰的数目随着热处理时间的加长而增加和加强。利用类氢模型和有效质量理论拟会和计算,可以证明与氧有关的热施主很可能是双重电荷施主。这些双重施主有多种组态,它与450℃热处理的时间有关。

The intrinsic absorption spectra for Hg_(1-x)Cd_xTe thin samples with compositions of x=0.17~0.443 at 300K are measured, and the energy positions of the banb gaps for all the samples are determined with the method presented by Chu Junhao et al. in 1982 and 1983. It is found that α(E_g, 300K)=500+ 5600x, where a(E_g, 300K) is the absorption coefficient at the energy of band gap at 300 K. This is the operating curve for determing composition x by the method of infrared absorption. For a thick sample of Hg_(1-x)Cd_xTe...

The intrinsic absorption spectra for Hg_(1-x)Cd_xTe thin samples with compositions of x=0.17~0.443 at 300K are measured, and the energy positions of the banb gaps for all the samples are determined with the method presented by Chu Junhao et al. in 1982 and 1983. It is found that α(E_g, 300K)=500+ 5600x, where a(E_g, 300K) is the absorption coefficient at the energy of band gap at 300 K. This is the operating curve for determing composition x by the method of infrared absorption. For a thick sample of Hg_(1-x)Cd_xTe with unknown composition, the absorption edge might be at first measured at 300 K, and then the E_g(300K) might be obtained by extending the edge to a(E_x, 300K). The composition to be measured will be x=3.8158—1/2(13.9547-5.263E_g(300K)).

在室温下测量了组分x=0.170~0.443的Hg_(1-x)Cd_xTe薄样品的本征吸收光谱,并采用参考文献[4][5]中的方法确定其禁带宽度,发现与禁带宽度相当的能量处的吸收系数为α(E_g,300K)=500+5600x。把该式作为用红外光吸收法测定Hg_(1-x)Cd_xTe组分的工作曲线,先测出未知组分的Hg_(1-x)Cd_xTe厚样品的吸收边,并延长到α(E_g,300K)处,得到E_g(300K)后,即可求得待测组分:
