Accurate measurements of the lattice constant of cadmium mercury telluride (Cd x Hg 1− x Te, or CMT) grown by molecular beam epitaxy (MBE) are reported for the composition range 0⩽ x

Uniform layers of cadmium mercury telluride have been grown on inhomogeneous cadmium zinc telluride substrates by molecular beam epitaxy so that a single epitaxial layer experiences a laterally varying lattice mismatch. The lateral variations of laye

Growth of epitaxial layers of Cd x Hg 1− x Te (CMT) onto Cd 1− y Zn y Te (CZT) substrates is widely reported as being performed in order to minimize misfit dislocations at the growth interface. The lattice parameters of CdZnTe alloys with y ∼0.

Epitaxial layers of CdxHg1−xTe (CMT) are grown onto Cd1−yZnyTe (CZT) substrates in order to minimize misfit dislocations at the growth interface. For long wavelength focal plane array infrared detector requirements x = 0.22 CMT is nominally latti

We have measured, by X-ray diffraction, the deformation of uniform cadmium mercury telluride layers epitaxially grown on cadmium zinc telluride substrates with varying zinc concentration. It is then possible, within the same sample, to clearly identi

A simple procedure is described for mapping of lattice parameter and X-ray rocking curve width across Cd 1− y Zn y Te (CZT) substrates and Cd x Hg 1− x Te (CMT) epitaxial layers. It is shown how screening of the crystallinity and composition of C

Metal - oxide - semiconductor field-effect transistors (MOSFETs) on CdTe/HgTe/CdTe heterostructures are fabricated with silicon dioxide gate insulators. In these devices, the density of the quasi two-dimensional electron gas in the HgTe quantum well

The growth of cadmium mercury telluride (CMT) by molecular beam epitaxy requires control of the substrate temperature within a narrow window of a few degrees for growth of twin‐free layers on the (111)B and (211)B orientations. It is shown that a t

The authors consider interband and intersubband absorption in HgCdTe/CdTe single quantum well structures. By measuring the transmission in an internal reflection geometry with and without a metallized surface and polarized light, they study the depen
