Abstract
Nanowire technology can offer unique opportunities for realization of different 3D device structures, ranging from 1D nanowires for radial LEDs to the formation of c-oriented dislocation-free planar structures for vertical microLEDs, as well as to self-forming dislocation-free and atomically smooth photonic cavity structures. In this talk I will describe nanowire-mediated formation of microLEDs via controlled reshaping of ternary InGaN pyramids yielding c-oriented relaxed and dislocation-free InGaN-platelets that form the basis for vertical InGaN microLEDs emitting all three RGB-colors. I will also describe recent progress in the self-formation of atomically smooth and dislocation-free hexagonal prism structures acting as photonic cavity structures.
