Room temperature operation of InxGa1-xSb/InAs type-II quantum well infrared photodetectors grown by MOCVD

Very Long Wavelength InxGal . xAs / GaAs Quantum Well Infrared Photodetectors

We demonstrate the first long-wavelength (Xc= 20 pm) quantum WN infrared photodetector using non-lattice matched InxGaj-xAs/GaAs materials system. High optical gains (low capture probabilities) were achieved by using GaAs as a barrier material in this system. The dctcctivity has been found to be comparable to those achieved with the usual lattice matched GaAs/AlxGal-XAS detectors.

Assessment of quantum dot infrared photodetectors for high temperature operation

Investigation of the performance of quantum dot infrared photodetectors QDIPs in comparison to other types of infrared photodetectors operated near room temperature is presented. The model is based on fundamental performance limitations enabling a direct comparison between different infrared material technologies. It is assumed that the performance is due to thermal generation in the active reg...

Modeling of High Temperature GaN Quantum Dot Infrared Photodetectors

In this paper, we present calculations for different parameters of quantum dot infrared photodetectors. We considered a structure which includes quantum dots with large conduction-band-offset materials (GaN/AlGaN). Single band effective mass approximation has been applied in order to calculate the electronic structure. Throughout the modeling, we tried to consider the limiting factors which dec...
