In mineralogy, epitaxy is the overgrowth of one mineral on another in an orderly way, such that certain crystal directions of the two minerals are aligned. This occurs when some planes in the lattices of the overgrowth and the substrate have similar spacings between atoms. If the crystals of both minerals are well formed so that the directions of the crys… WebOct 15, 2024 · Here, we review epitaxial growth and layer-transfer techniques for monolithic integration of dissimilar single-crystalline materials for application in advanced electronic and photonic devices.
