Abstract:The synthesis of semiconductor nanowires (NWs) with near-infrared light-absorbing and light-emission properties is presented. Gallium (Ga)-induced vapor−liquid−solid growth is used to produce GaAs/GaInNAs/GaAs core−multishell NWs on a 2 in. Si(111) wafer using plasma-assisted molecular beam epitaxy. The GaInNAs shell consists of 11% indium (In) and varying compositions of nitrogen (N) of up to 1.9%. The NWs serve as an antireflective material, showing that the entire substrate is black.
