Paper Abstract

We have demonstrated the use of bulk antimonide based materials and type-II antimonide based superlattices in the development large area long wavelength infrared (LWIR) focal plane arrays (FPAs). Barrier infrared photodetectors (BIRDS) and superlattice-based infrared photodetectors are expected to outperform traditional III-V MWIR and LWIR imaging technologies and are expected to offer significant advantages over II-VI material based FPAs. Our group has developed a novel complementary barrier infrared detector (CBIRD) which utilizes properties unique to the antimonide material system to incorporate unipolar barriers on either side of a superlattice absorber region. We have used molecular beam epitaxy (MBE) technology to grow InAs/GaSb CBIRD structures on large area 100mm GaSb substrates with excellent results. Furthermore, we have fabricated initial 1024x1024 pixels superlattice imaging FPAs based on the CBIRD concept.
