Abstract
The InAs/GaAs p-i-p quantum dots infrared photodetectors (QDIPs) were detailedly demonstrated by Apsys software in the paper. The device consists of Al0.3Ga0.7As/GaAs supper lattice (SL) and InAs quantum dots (QDs) embedded in In0.15Ga0.85As, which make device has an advantages of low dark current and large photocurrent at room temperature (300K). The dark current and photocurrent of the device with different InAs QDs density and the number of Al0.3Ga0.7As/GaAs SL is discussed detailedly.
