Abstract
Method of diffusing zinc into gallium arsenide and aluminum gallium arsenide. A wafer of gallium arsenide or aluminum gallium arsenide is placed in close proximity to a quantity of granular zinc gallium arsenide. The assemblage is heated in an open-tube furnace in the presence of flowing nitrogen to vaporize zinc whereby zinc diffuses into the gallium arsenide or aluminum gallium arsenide wafer without eroding the surface.
