Abstract

A grown crystal structure comprises a single crystal of semiconductive material having a given lattice constant grown on a spinel crystal substrate having a different lattice constant. A substance is added to one or both of the crystals and has suitable properties relative to the crystals to effectively reduce lattice strains developed in the grown crystal structure due to mismatch of the lattice constants of both crystals.
