New Techniques for Growing Highly-Homogeneous Quaternary Hg1-x-yCdxMnyTe Single Crystals

Abstract
An advanced crystal growth method named the “modified two-phase mixture method” has been developed as a new way of producing highly-homogeneous large single crystals of quaternary semimagnetic semiconductor Hg1-x-y Cd x Mn y Te alloys. A comparison of the results with the usual Bridgman method and the modified zone melting method shows that the new method gives the best homogeneity in the growth direction and is promising for the crystal growth of multinary compound semiconductors with temperature-composition phase diagrams having a wide separation of the liquid and solid phase mixtures.
