High operating temperatures infrared photo detectors are needed for improving the performance of these systems. To obtain high device performance at higher temperatures, the thermally generated noise required to be reduced. Minority-carrier extraction and exclusion techniques are the approaches for decreasing the thermal noise of infrared systems. In the present work, an Hg1-xCdxTe photodiode was studied and simulated for operation in the MWIR region. A simulation of the device was carried out by using ATLAS software from SILVACO in order to study the performance of the photo detector at near room temperatures.
