Semiconductor nanowires have recently stimulated great interest due to their attractive and potentially very useful properties, originating from features such as carrier confinement, high surface to volume ratio, and morphology/crystal structure unique to their nanoscale dimension and bottom-up growth process. These properties lead to many possible applications such as room temperature ballistic conductors for high-frequency/high-powered integrated circuits, UV/visible/IR nanolasers and waveguides, as well as sensors for chemical and biological agents. The systematic assembly and integration of nanowires into electrical and electro-optical devices, however, remain a formidable challenge. The goal of this project is to address this problem and develop a novel 2D individually-addressable nanowire array to serve as the platform for future device applications.
