Tunable Bandwidth Quantum Well Infrared Photo Detector (TB-QWIP)

Abstract

In this thesis a tunable bandwidth quantum well photo- detector (TB-QWIP) is fabricated and experimentally characterized. The designed detector is based on the Stark effect with two quantum step wells arranged opposite to each other to simultaneously achieve both blue- and red-shift of the absorption peak for either direction of the bias. The characterization of the TB-QWIP is based on absorption measurement with Fourier Transform Infra Red (FTIR) spectroscopy, current versus applied voltage (I-V) measurement with a semiconductor parameter analyzer, and photo current spectroscopy. The measured IR absorption peaks found at room temperature 8.8 microns and 10.0 microns, are in good agreement with designed values.
