摘　　要：本文详细地分析了一种新型光电探测器——内调制光敏管的物理特性,考虑了表面态和通道空穴准费米势分布的影响。导出了通道内空穴浓度和空穴准费米势沿通道的分布,和耦合系数与栅压的关系,它们与实验结果符台得较好。Physical characteristics of a new kind of photodetectors,the intramodul- ated photosensor,is analyzed in detail,the effects of the surface states and distribution of the hole qusifermi potential in the passage is taken into acco- unt.The coupling coeficient of the passage,the distribution of the hole con- centration and qusifermi potential of the hole along the passage,and the opt- oelectronic characteristics are derived.It is in good agreement with the ex- perimental measurement results.
