摘要
Heterojunction nanowires were fabricated via a vapor-liquid-solid growth mechanism in a metal organic chemical vapor deposition system. The structure consisted of a n-type GaN:Si core surrounding by a distinct p-type AlGaN:Mg shell. Transmission electron microscopy revealed that the nanowires were free of extended defects. Photoluminescence measured a strong UV emission peak. Additionally, sources of mid-gap transitions are linked to surface states on the nanowire surface.
