Growth and Optical Properties of Self‐Organized Au2Si Nanospheres Pea‐Podded in a Silicon Oxide Nanowire
Source abstract
Abstract
Silicon‐based nanowires with embedded self‐assembled chains of gold silicide nanospheres (Au2Si@SiONW) have been prepared by annealing Si/Au bilayers. The diameter, number density, and length of the wires can be controlled by adjusting the bilayer thickness. The composite material displayed a new sharp photoluminescence peak thought to result from inter‐band transitions in the “pea‐podded” (see Figure) gold silicide crystals.
