PROCESS FOR ELABORATING TERNARY OR QUATERNARY SEMICONDUCTOR COMPOUNDS

摘要

Process for producing ternary or quaternary semiconductor compounds, particularly of formula Cd Hg Te or Cd Hg Te Se. It comprises the following stages: forming a homogeneous mixture having a precise composition and corresponding to the compound to be obtained, of Cd Te and Hg Te powders in the case of the ternary compound Cd Hg Te and Cd Te Se and Hg Te or Cd Te and Hg Te Se powders in the case of the quaternary compound Cd Hg Te Se; the mixture is compacted by applying a pressure; the thus compacted mixture undergoes thermal interdiffusion treatment; the recrystallization of the compound in monocrystalline form takes place by a single passage through the solvent zone.
