Abstract

We present four new types of III-V quantum well infrared photodetectors (QWIPs) operating in photoconductive (PC) and photovoltaic (PV) modes for the wavelength range from 2 to 14 μm. These dual-mode (DM) operation QWIPs were grown by the MBE technique using GaAs/AlGaAs, AlAs/AlGaAs, and InGaAs/InAlAs material systems. Based on the bound-to-miniband (BTM) and the enhanced bound-to-continuum (BTC) intersubband transition schemes, these detectors provide the features of large absorption coefficient, low dark current, and high detectivity in the wavelength of interest, and show promising for use in large area IR focal plane array image sensor applications.
