ABSTRACT:
A method of growing semiconductor compounds which are formed from elements of group III with elements of group V by liquid phase epitaxy. A suitable solvent is provided in contact with a source of the compound to be grown, the solution is heated to a predetermined temperature and the solute is allowed to come to equilibrium with the solvent. The solution is then subjected to a rapid, relatively small decrease in temperature to produce supersaturation of the solution. The temperature is then maintained substantially constant and, after a predetermined first period of time at the constant temperature, the solution is brought into contact with a substrate on which the compound is to be grown for a predetermined second period of time.
