Abstract
A method of synthesizing zinc selenide crystals. The method includes forming an aqueous growth medium by combining a mineralizer solution of an alkali nutrient with a feedstock including zinc and selenium. A seed crystal is added to the growth medium. The aqueous growth medium and seed crystal are pressurized and a thermal gradient applied such that a temperature of a first portion of the aqueous growth medium is greater than a second portion of the aqueous growth medium. The zinc and selenium are dissolved into the mineralizer solution from the feedstock in the first portion of the aqueous growth medium and spontaneously forms at least one single crystal of zinc selenide on the seed crystal in the first portion of the aqueous growth medium.
