论文摘要
对电子纳米材料的研究最近越来越关注具有非常规弯曲几何形状的结构的合成，包括平面系统中的弯曲电线和通过滚动纳米膜获得的三维体系结构。这些几何形状的包含导致了一系列新型效应的预测和观察，这些效应要么是由于形状驱动的电子运动的修饰，要么是由于特殊的限制效应引起的电子和磁性的内在变化。此外，由于机电耦合在固体中所起的重要作用，曲率通常会产生的局部菌株也触发了新现象的出现。在这里，我们回顾了在发现纳米级的这些形状，约束和应变诱导的曲率效应方面的最新发展，并讨论了它们在电子和自旋设备中的潜在用途。
Research into electronic nanomaterials has recently seen a growing focus into the synthesis of structures with unconventional curved geometries including bent wires in planar systems and three-dimensional architectures obtained by rolling up nanomembranes. The inclusion of these geometries has led to the prediction and observation of a series of novel effects that either result from shape-driven modifications of the electronic motion or from an intrinsic change of electronic and magnetic properties due to peculiar confinement effects. Moreover, local strains often generated by curvature also trigger the appearance of new phenomena due to the essential role played by electromechanical coupling in solids. Here we review the recent developments in the discovery of these shape-, confinement- and strain-induced curvature effects at the nanoscale, and discuss their potential use in electronic and spintronic devices.
