Lithographically Patterned Quantum Dot Structures for Infrared Detection

Abstract

Significant progress was made to further advance the quantum well infrared photodetector (QWIP) technology in two areas: 1) designing, demonstrating, and understanding voltage tunable two-color QWIPs, and 2) understanding the light coupling mechanism in the so-called quantum grid infrared photo-detectors. We have also been working on imprint technology to create pillars which can be used to enhance the performance of the photo detectors. The NIL molds with different period and different shape of the pillars have been created. Implementation of the small pillars to photo detectors are in progress.
