TBA-enabled spin-coating of a percolatively connected GO nanosieve for thru-hole epitaxy: tuning GO flake stacking and coverage to control GaN nucleation
Gunhoon Beak, Changwook Dong, Minah Choi +3
We report a spin-coating-based approach for forming a percolatively connected graphene oxide (GO) nanosieve on SiO-patterned sapphire substrates, where the addition of tetrabut…

Orientation disparity in GaN/graphene/-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…
