Abstract
This paper presents a recent study on the synthesis of AlN nanowires. AlN nanowires were successfully prepared on sapphire substrate by the Al-Sn flux method. The obtained nanowires were hundreds of nanometers in diameter and tens of microns in length. The results of transmission electron microscopy (TEM) show that the growth direction of AlN nanowires was perpendicular to the C axis. The photoluminescence (PL) spectrum of AlN nanowires shows a broad peak, which is ascribed to the defect levels in the AlN bandgap. This work provides a novel method for growing AlN nanowires, which offers a potential material for the application of photoelectron devices.
