Abstract:We present a technique for direct, in-situ, integration of semiconductor nanowires into photodetectors and other optoelectronic devices. In particular, CdSe nanowire growth off metallic electrodes containing catalyst nanoparticles in solution is initiated and controlled by inducing electric fields at the electrode surfaces.
