ABSTRACT Resonant tunneling has been demonstrated through a variety of molecular‐beam epitaxially grown HgCdTe heterostructures. Single‐quantum‐well, double‐barrier resonant tunneling structures with a large variation in quantum well widths and barrier thicknesses were investigated. We also present results on transport through two strongly coupled superlattices, which exhibit negative differential resistance due to energy filtering by the superlattice minibands.

    ABSTRACT: Selected properties of HgTe‐CdTe superlattices are re‐examined in light of the new consensus that the valence‐band offset is large. We conclude that while the cutoff wavelength for infrared detectors remains easier to control in superlattices than in the corresponding Hg 1-x Cd x Te alloy, the advantage is less than was predicted earlier assuming a small offset. The reduction of tunneling noise and minority carrier collection efficiency are discussed on the basis of revised electron and hole masses in the growth direction.

    ABSTRACT: The purpose of this paper is to survey and assess recent trends in the field of detector materials for infrared focal plane arrays (IRFPAs) applicable in high-performance thermal imaging systems. Considered are II-VI, III-V and IV-VI compounds (including hetero structures and superlattices) with respect to their actual and potential performance, reliability and producibility. Addressed are growth methods for thin films of high uniformity as regards physical, optical, and electrical properties. The main efforts are found presently to concentrate on establishing growth methods for material systems and structures appropriate for more efficient manufacturing of IRFPAs. It is concluded that HgCdTe continues to be the most important material for infrared imaging in the wavelength region between 8 and 12 μm.
