Using our own computer program, we determined the spatial distribution of lattice strains in the HgCdTe heterostructure grown on a GaAs substrate. Lattice stress resulting from lattice mismatch between the substrate and the epitaxial layer and bendin

Most of the HgCdTe infrared detectors are fabricated by mesa geometry using a wet chemical or plasma etching techniques. The mesa definition etch process induces undesirable changes in HgCdTe surface properties. In narrow bandgap materials these surf

We investigate the high-operating temperature performance of InAsSb/AlSb heterostructure detectors with cutoff wavelengths near 5 μm at 230 K. The devices have been fabricated with different types of absorbing layers: nominally undoped absorber (wit

The work reports on mid-wavelength infrared HgCdTe barrier detectors with a zero valence band offset, grown by metal organic chemical vapour deposition on GaAs substrates. The experiments indicate the influence of the barrier on electrical and optica

The paper concerns the correlations between low-frequency noise and dark currents in the p-i-n diode made of type-II InAs/GaSb superlattice material designed for mid-wavelength infrared. It is shown that diffusion and generation-recombination current

In the last decade, new architecture designs such as nBn devices or unipolar barrier photodiodes have been proposed to achieve high-operating temperature (HOT) detectors. This idea has been also implemented in HgCdTe ternary material systems. However
