(a) Schematic of the exfoliation method - a liquid gallium droplet is isolated and its passivation oxide is directly transferred onto a substrate. (b) Microscope image of the Ga\(_2\)O\(_3\) film deposited on thermally oxidised Si substrate after annealing at 250\(^{\circ }\)C for 1 hour. (c) Atomic Force Microscopy linescans taken across thin-film oxide to substrate edges in two different areas.
