Abstract
A photovoltaic six stacked In0.15Ga0.85As/GaAs quantum dot infrared photodetector detector (QDIP) with a Al0.3Ga0.7As single-side blocking layer is investigated with simulation software. The current-voltage (I-V) characteristics curve is simulated including dark current. Compared with dark current, zero-drift is found in photocurrent. The voltages at which zero-bias offset occur is studied with different power of illumination.
