| Abstract: |
| The single crystal bismuth nanowire arrays grown along [0112] with the diameter of 30 nm was synthesized in the pore of anodic aluminum oxide templates through electrodeposi-tion process. The temperature dependent electric conductance of Bi nanowire arrays was measured from 78 K to 320 K. We found that the semimetal-to-semiconductor transition happened around 230 K for 30 nm Bi nanowires oriented along [01112] and the electric con-ductance of the nanowires had a strong temperature dependence. |

| 摘要: |
| 采用电沉积的方法在多孔氧化铝模板中合成了直径为30 nm且沿着[0112]方向生长的单晶铋纳米线，测量了纳米线电导随着温度78～320 K变化的关系曲线. 结果发现，其半金属半导体转变的温度为230 K，且纳米线的电导有很强的温度依赖性. |
