Thermodynamic Properties of Mercury-Zinc Telluride Solid Solutions and Melts

汞、锌和碲的分压将由汞和碲化锌在300℃至1000℃之间形成的固溶体组成来测定。这将通过测量与固体或液体样品共存的气相在200至700纳米之间的光学吸光度来完成。化学势和熔化温度，以及其他热力学性质，将被确定。这些数据在文献中没有，在处理这些技术上重要的材料时需要这些数据，这些材料正在使用或考虑用于红外探测器。这些数据对于指导晶体生长和随后的退火以控制缺陷浓度以及随后的电子和光学性质具有重要意义。

The partial pressures of mercury, zinc, and tellurium will be determined for compositions of the solid solutions formed between mercury and zinc tellurides between 300 and 1000 C. This will be accomplished by measuring the optical absorbance between 200 and 700 nanometers of the vapor phase coexisting with a solid or liquid specimen in a sealed cell of fused silica. The chemical potentials and melting temperatures, as well as other thermodynamic properties, will be determined. The data are not available in the literature, and are needed in the processing of these technologically important materials, which are being used or considered for application in infrared detectors. The data will be important in guiding the efforts in crystal growth and subsequent annealing to control defect concentrations, and subsequently the electronic and optical properties.
