Abstract
Abstract EPITAXIAL LAYERS OF III-V COMPOUNDS ARE GROWN ON THE FACING SURFACES OF A PAIR OF PARALLED, SPACED-APART WAFERS BY FORCING A SMALL QUANTITY OF A SOLUTION SATURATED WITH A III-V COMPOUND BETWEEN THE WAFERS FOR SELECTED TIME. LOWERING THE TEMPERATURE OF THE SOLUTION PRECIPITATES THE III-V COMPOUND EPITIAXIALLY ONTO THE ADJACENT SURFACES OF THE WAFERS.
