Thermodynamic description of the systems Cd-Te, Hg-Te and Cd-Hg-Te using the model of associated liquid solution

Indium-Hg vacancy interactions in Hg 1 ,,Cd,Te measured by perturbed angular correlation

The interaction of mercury vacancies with dopant indium atoms in Hg0,7&d0.t,Te was studied using the perturbed ‘y”/ angular correlation (PAC) technique+ Two dominant PAC signals, characterized by quadrupole interaction strengths YQ~ = 83 MHz and yoL = 91 MHz and asymmetry parameters v1 = r/2 = 0.08, were observed and attributed to one or more In-Vu, complexes. The complexes appeared after annea...

Evidence for depinning of a Wigner crystal in Hg-Cd-Te.

We report measurements of the nonlinear current-voltage characteristics on low-carrierconcentration n-type samples of Hg076Cd024Te at high magnetic fields and low temperatures. We find the onset of nonlinear conductivity occurs at applied electric fields of less than 1 mV/cm. The effect can be easily distinguished from sample heating and is consistent ~ith collective transport produced by the s...

Particulate Contacts to Si and CdTe:Al, Ag, Hg-Cu-Te, and Sb-Te

Our team has been investigating the use of particle-based contacts in both Si and CdTe solar cell technologies. First, in the area of contacts to Si, powders of Al and Ag prepared by an electroexplosion process have been characterized by transmission electron microscopy (TEM), TEM elemental determination X-ray spectroscopy (TEM-EDS), and TEM electron diffraction (TEM-ED). These Al and Ag partic...

Prototype Imaging Cd - Zn - Te Array Detector

We describe initial results of our program to develop and test Cd-Zn-Te (CZT) detectors with a pixellated array readout. Our primary interest is in the development of relatively thick CZT detectors for use in astrophysical coded aperture telescopes with response extending over the energy range ∼ 10 − 600 keV. The coded aperture imaging configuration requires only relatively large area pixels (1...
