Research on Improved II-VI Crystals.

Abstract

Vapor phase growth of single-crystal boules of CdTe, CdSe, ZnTe, and CdS was attempted by the seed-growth method using a capillary leak to maintain a stoichiometrically-proportioned vapor composition during the growth process. Although a measure of success was attained, difficulties arose such as formation of extraneous nucleation and occurrence of inclusions of SiO2 particles. Single-crystal growth at relatively high growth rates over at least a limited seed area was obtained for each compound for the complete length of the boule. Improved techniques should eliminate much of the difficulty but some modifications of the method may be necessary to attain complete success. An analysis of multiple twinning in CdTe and ZnTe crystals occurring during the growth process is also given. (Author)
