摘要: In this paper, transfer function of a colloidal quantum dot infrared photodetector (CQDIP) is derived considering the system rate equations, to study modulation response CQDIP. The presented models reaction different frequencies input optical signals. Theoretical results obtained from our model are in excellent agreement with reported experimental data by Clifford et al. , Konstantatos and Sargent, Miri Therefore, validity proven for these reasons. Our analysis shows that provides bandpass frequency response, converting signals electrical lying within its working region, displaying transparent behavior beyond region. This helps designers selecting proper materials fabricate suitable devices desired region an eye toward carrier lifetime intersubband energy levels.
