A technique to measure the electric charge on the mesa sidewalls of small infrared detector pixels

Phase 1 SBIR

Agency: Army
Topic: A13-042
Budget: 06/27/13 - 12/31/13
PI: Dr. Mani F. Sundaram

We propose a simple and elegant technique to directly measure the electric charge on the surfaces of small pixels of III-V and II-VI infrared detectors. Such charges arise from minority-carrier inversion or majority-carrier accumulation layers caused by surface states and exist as 2-dimensional electron or hole gases on the mesa sidewalls. They ...

PI: Dr. Mani F. Sundaram

In Phase I we developed a novel infrared photodiode based on Type-II InAs/GaSb strained layer superlattices (SLS) that showed pingpong dualband action, wherein the spectral response of the diode was switched between extended midwave (~ 8 micron cutoff) and longwave (~ 10 micron cutoff) infrared by the polarity of the voltage bias applied across ...

A Scheme to Reduce Dark Current in SLS FPAs

Phase 1 SBIR

Agency: Missile Defense Agency
Topic: MDA11-005
Budget: 02/01/12 - 07/31/12
PI: Dr. Mani F. Sundaram

Longwave infrared focal plane arrays (FPAs) based on Type-II InAs/GaSb-based strained layer superlattice (SLS) photodiodes show good performance at the current time. A key remaining challenge is the reduction of dark current, dominated by pixel surface leakage in FPAs and low minority carrier lifetime in the bulk material. We propose to address ...

Phase 1 SBIR

Agency: Missile Defense Agency
Topic: MDA10-012
Budget: 07/01/11 - 01/03/12
PI: Dr. Mani F. Sundaram

We propose to bandgap engineer the InAs/GaSb/AlSb material system to realize a dualband focal plane array (FPA) made up of stacked multi-barrier Type-II strained layer superlattice (SLS) photodiodes. Two longwave infrared spectral bands will be imaged in alternate frames by using a readout multiplexer that flips the voltage bias across the FPA ...
