我们通过选择线上不同的接触位置形成金属-ZnO 接触，研究了 ZnO 微/纳米线中形变诱导压电势（压电势）对其电传输特性的影响。当ZnO线不均匀变形时，不同位置的局部压电势分布对载流子传输特性有显着影响且变化趋势明显。这项研究通过控制局部接触位置和接触尺寸，对于理解基于纤锌矿材料纳米线的压电器件的特性具有广泛的影响。
We present a study on the effect of deformation induced piezoelectric potential (piezopotential) in a ZnO micro/nanowire on its electrical transport properties by choosing different contacting locations on the wire to form a metal-ZnO contact. When a ZnO wire is under nonuniform deformation, the local piezopotential distribution at different positions shows significant effect on and distinct trend of variation in the charge carrier transport characteristic. This study has a broad impact on understanding the characteristics of piezotronic devices based on nanowires of wurtzite materials by controlling local contact position and contact size.
