Slanted n-ZnO/p-GaN nanorod arrays light-emitting diodes grown by oblique-angle deposition
High-efficient ZnO-based nanorod array light-emitting diodes (LEDs) were grown by an oblique-angle deposition scheme.Due to the shadowing effect, the inclined ZnO vapor-flow was selectively deposited on the tip surfaces of pre-fabricated p-GaN nanorod arrays, resulting in the formation of nanosized heterojunctions.The LED architecture composed of t
