Surface and interfacial study of half cycle atomic layer deposited Al2O3 on black phosphorus
The interfacial chemistry of half cycle ALD of Al2O3 on black-P was examined. The ALD process increases the extent of oxidation of the black-P surfaces with an initial thin oxide. Several incubation cycles are needed for the ALD Al2O3 on black-P surfaces. Surface oxidation of the black-P enhances the nucleation of Al2O3 on black-P.
