Diamond heteroepitaxial lateral overgrowth
WebHere, we describe a method for lateral overgrowth of low-stress single crystal diamond by chemical vapor deposition (CVD). The process is initiated by deposition of a thin (550 nm) (001) diamond layer on Ir-buffered a-plane sapphire. The diamond is partially masked by periodic thermally evaporated Au stripes using photolithography. WebFeb 22, 2016 · Toward this task, in addition to the selection of a substrate material for Ir deposition and the optimization of the Ir deposition, the epitaxial lateral overgrowth (ELO) of diamond, which is a well-known method of significantly reducing dislocations in other …
