Abstract
The performance of long wavelength infrared high quality n+‐on‐p HgCdTe photodiodes is reexamined theoretically. It is shown that the performance can be explained taking into account only thermal generation governed by the Auger mechanism. The investigations are carried out for photodiodes operated in a temperature range between 300 and 50 K. The effect of doping profiles on the photodiode parameters (R0A product, IV characteristic, photoelectrical gain and noise) is solved by forward‐condition steady‐state analysis. The theoretical predictions of photodiode parameters are compared with experimental data obtained at the Laboratoire dElectronique de Technologie et dInstrumentation (Grenoble, France). Excellent agreement between both types of results has been achieved.
