在1200 ℃的氨/氮气氛中，通过蒸发铝粉成功地合成了六方结构的氮化铝纳米带。所制备的AlN纳米带具有宽度为30-500 nm且长度为约100 μ m的矩形横截面。光学表征表明，尽管其纳米带的几何形状，AlN纳米带的振动模式与AlN薄膜的振动模式一致。AlN的这种纳米带几何形状对于未来纳米电子学中GaN基纳米异质结构的构建可能是重要的。
Aluminum nitride nanobelts with hexagonal structure were successfully synthesized by evaporating aluminum powder in ammonia/nitrogen atmosphere at 1200 degreesC. The as-prepared AIN nanobelts have a rectangular cross section with a width of 30-500 nm and length of about 100 mum. The optical characterization indicates that the vibration modes of the AIN nanobelt agree well with those of AIN film despite its nanobelt geometry. This nanobelt geometry of AIN could be important for the construction of GaN-based nanheterostructures in future nanoelectronics.
