摘要
从理论上考虑了碲镉汞长波光电二极管的主要电流机制 ,并采用合适的参数对R0 A进行了计算 .结果表明 ,由于隧道电流的限制 ,对于一定的衬底浓度 ,选择 p区掺杂的浓度不宜过大 ,反之亦然 .计算得到了优化掺杂浓度与衬底浓度的关系和相应的R0
By considering the main current mechanism in the long-wavelength HgCdTe photodiode, theoretical calculation of R 0A was done by choosing proper parameters. Calculations show that, given n side substrate concentration, the p side doping concentration should not be too large on considering the limitation of the tunneling current,and vice versa. The relation of optimal concentration with the substrate concentration was calculated and the corresponding R 0A was also obtained.
