摘要
研究了组分x=0.18～0.50的N-Hg_(1-x)Cd_xTe样品在0.3～4.2K低温区和0～7T磁场强度下的过热电子效应,结果表明过热电子效应强烈依赖于样品的组份、电学参数以及材料的晶体质量。
The hot electron effect in a number of N-type Hg_(1-x)Cd_xTe samples with different compositions (x=0.18～0.50) is investigated at low temperatures 0.3～4.2 K and under magnetic fields 0～7 T. Nonlinear Ⅰ-Ⅴ relations are observed. The experiment results denote that the hot electron effect strongly depends on the composition, the electron conoentration, mobility and even the orystal quality of the samples.
