周期性曲面中的低温电阻率异常
Low-Temperature Resistivity Anomalies in Periodic Curved Surfaces
摘要：
从理论上研究了周期性曲率对波纹半导体薄膜电阻率的影响。曲率诱导电位的存在会影响限制在弯曲薄膜中的电子的运动，从而导致在两个几何参数的特定值下显著的电阻率增强：表面电阻率的振幅和周期。为了观察在实际实验中的波纹引起的电阻率增强的两个参数的最大值被量化，通过采用现有的材料常数。
英文摘要：
Effects of periodic curvature on the the electrical resistivity of corrugated semiconductor films are theoretically considered. The presence of a curvature-induced potential affects the motion of electrons confined to the thin curved film, resulting in a significant resistivity enhancement at specific values of two geometric parameters: the amplitude and period of the surface corrugation. The maximal values of the two parameters in order to observe the corrugation-induced resistivity enhancement in actual experiments are quantified by employing existing material constants.
