Abstract

Semiconductor nanostructures confined in two- or three-dimension have attracted significant attention over the past decade due to their unique mechanical, electronic, optical, and magnetic properties and represent a broad class of building blocks for functional device architectures. Critical to their fundamental properties and device functionality are the precise morphology and dimensionality control of semiconductor nanostructures, which has been a forefront research area and will lead to big impact on progress of nanoscience and nanotechnology offering opportunity for manipulating and fabricating artificial nanostructures that might not even exist in nature with desired property and functionality. In this talk, I will present a few recent highlights from what I have been involved for realization of hybrid semiconductor nanostructures. I will start from materials standpoint and show how to achieve meticulous control of hybrid nanostructures including defects, crystallinity and compositions based on bottom-up chemical synthetic strategy and applications.
