Orientation disparity in GaN/graphene/$m$-sapphire: control-based re-examination of thru-hole epitaxy

Su Young An, Hyunkyu Lee, Gunhoon Beak +8

The crystallographic orientation of films grown on 2D-masked substrates is often used to infer the pathway among remote, van der Waals, and thru-hole (pinhole-seeded) epitaxy. Howe…
