HgCdTe as a playground for massless fermions

, 2017
International audienceBulk films and heterostructures based on HgCdTe compounds can be engineered to fabricate “gapped-at-will” structures. Therefore, 1D [1], 2D [2] and even 3D [3] massless particles can be observed in topological phase transitions ...

Mbe Growth and Characterization of Lwir HgCdTe

, 1989
We have grown high-mobility LWIR HgCdTe thin films on CdTe substrates, using molecular beam epitaxy (MBE). The structural, optical, and electrical properties of these epilayers were determined by SEM, DCRC, FTIR, and Hall effect measurements.

Nanoimprint induced electrical type conversion in HgCdTe

, 2010
We report supporting evidence that is consistent with p- to n-type conversion of HgCdTe that is induced by surface indentation, as the progress towards the fabrication of photovoltaic infrared detectors by direct imprinting.

Photoplasticity in HgCdte

, 1983
A time delay has been observed in HgCdTe in the photoplastic response of these crystals. Both the magnitude of the time delay and the total change in stress, Δσ, are dependent on the wavelength of the light.

Electrical type conversion of p-type HgCdTe induced by nanoimprinting

, 2011
A nanoimprinting method was used to generate square imprints and arrays of imprints ranging in lateral dimension from 1 μm to 50 μm in p-type HgCdTe. Laser Beam Induced Current (LBIC) characterization shows electrical type conversion around each imprint ...

Ultrafast photoconductivity dynamics in narrow-gap HgCdTe films

APL Materials
Mercury cadmium telluride (Hg1−xCdxTe or MCT) is the premier material for infrared detection. However, despite its importance, studies exploring the ultrafast photoresponse in this semiconductor alloy are limited.
