ABSTRACT:
A method of preparing an AlInAs/GaAs hetero-structure includes forming an Al.sub.1-x In.sub.x As (0<x<1) buffer layer in an amorphous state on a GaAs substrate, annealing the amorphous buffer layer to crystallize the buffer layer into a single crystal buffer layer, and forming a single crystal Al.sub.1-x' In.sub.x' As (0<x'<1) active layer on the single crystal buffer layer.
