Preparation and Properties of Single Crystal ZnSe.
Abstract
Growth of ZnSe has been investigated by a variety of techniques. Polycrystalline boules of this material have been pulled from the stoichiometric melt by the liquid encapsulated Czochralski (LEC) technique. Single crystals have been produced by chemical vapor transport (CVT) with iodine vapor and by a modified Bridgman method suggested by Fischer under high pressure. LEC Czochralski boules grown from Cerac starting materials were polycrystalline. Cerac ZnSe was transported through a temperature gradient at 820C by I2 vapors. A general reduction in all impurities was determined by mass spectrographic analysis. Crystal quality is good in the lower half of Bridgman boules.
