Ferroelectricity in zinc cadmium telluride

Physical Review Letters, 1989
Ferroelectricity in ${\mathrm{Zn}}_{\mathrm{x}}$${\mathrm{Cd}}_{1\mathrm{\ensuremath{-}}\mathrm{x}}$Te was found from the temperature variation of the dielectric constant, and from the hysteresis loop. The Zn contents varied from 4% to 45%. No ferroelectricity was found in pure CdTe but all samples containing Zn had a second-order ferroelectric ...

Cadmium Telluride Nuclear Radiation Detectors

IEEE Transactions on Nuclear Science, 1975
The characteristics and performance of undoped high resistivity cadmium telluride detectors are compared to chlorine compensated counters. It is shown, in particular, that "undoped" CdTe Is in fact aluminium doped and that compensation occurs, as in silicon or germanium, by pair and triplet formation between the group III donor and the doubly charged ...

Ohmic contacts to p-type cadmium telluride and cadmium mercury telluride

Journal of Physics D: Applied Physics, 1983
The different techniques of making ohmic contacts to p-type CdTe are reviewed and discussed. Mercury telluride, whose work-function matches perfectly that of p-type CdTe, is shown to be more favourable than Au or Pt. The HgTe contacts deposited by close spacing isothermal growth present a room temperature specific contact resistance ten times lower ...

Sputtered indium-tin oxide/cadmium telluride junctions and cadmium telluride surfaces

Journal of Applied Physics, 1980
The properties of indium-tin oxide (ITO)/CdTe junction solar cells prepared by rf sputtering of ITO on P-doped CdTe single-crystal substrates have been investigated through measurements of the electrical and photovoltaic properties of ITO/CdTe and In/CdTe junctions, and of electron beam induced currents (EBIC) in ITO/CdTe junctions.

Photon-induced modifications in cadmium telluride/mercury cadmium telluride heterostructure interfaces

Applied Physics Letters, 2000
We report on photon-induced modifications in CdTe/MCT (cadmium telluride/mercury cadmium telluride) heterostructure interfaces formed by flash evaporated CdTe on to the bulk p-Hg0.8Cd0.2Te. Metal–insulator–semiconductor (MIS) test structures were processed and their electrical properties measured by capacitance–voltage (C–V) and current–voltage ...

Cadmium telluride and cadmium zinc telluride

2019
CdTe and CdZnTe crystals are employed for several applications such as IR imaging, X- and gamma ray detection, optical devices, and photovoltaics. These applications require that crystals show peculiar properties. On the other hand, phase diagrams suggest possible growth technologies.

Cadmium telluride module development

Solar Cells, 1991
Abstract Efficiencies of up to 12.3% have been achieved on small devices. It is expected that 14% efficiency will be exceeded on small devices by improving the fill factors on the present devices in the reasonably near future. Efficiencies in the range 16%–18% are expected to be achieved in the longer term. Modules of 6 W, approximately 929 cm 2 in

Determination of iron in cadmium and cadmium telluride

Talanta, 1966
A procedure is described for the determination of iron in the 10(-6)-10(-4)% range in cadmium and cadmium telluride. Acetylacetone is used for the separation of iron from cadmium, and the iron is determined spectrophotometrically with bathophenanthroline.

Cadmium telluride matrix gamma camera

Medical Physics, 1980
An experimental gamma camera that has significant performance has been designed, constructed, and tested. The new camera has a matrix of cadmium telluride semiconductors as the detecting medium. The detectors are located within the collimating holes (rather than behind them).

Cadmium Telluride Gamma Camera

IEEE Transactions on Nuclear Science, 1979
A small 4 cm X 4 cm prototype CdTe gamma camera has been constructed which demonstrates sensitivity and spacial resolution superior to the standard Anger camera. The camera is based on an array of linear solid state detectors contained within a laminar collimator which confines the field of view to one dimension.
