During the course of producing Hg1-x Cdx Te, the material is generally subjected to a variety of anneals under different Hg ambients. It has long been recogniized that these anneals result in vacancies in the material whose concentration is reflective of the anneal and its ambient. The resulnug defect structure of the material has significant impact on its use in focal plane arrays. Extensive work has been reported on material with x-O.2, and it can be said that this material is fairly well understood. The situation is less clear for other x values, however, making it difficult to predict defect properties of Hg1-x Cdx Te into new spectral regions.
