标题： Conductance properties of rough quantum wires with colored surface disorder

摘要： 相关无序对波局域化的影响引起了极大的兴趣。 鉴于对粗糙纳米线中量子输运研究的重要性，我们在此研究了基于反应矩阵方法的直接散射计算，探讨了彩色表面粗糙度如何影响二维量子波导的电导率。 计算结果与局域化长度和相关无序结构因子之间的理论关系进行了分析。 我们还检查并讨论了几种尚未被理论处理或超出现有理论有效范围的情况。 结果表明，通过彩色表面无序可以控制量子线的电导特性。 显示英文摘要

摘要： Effects of correlated disorder on wave localization have attracted considerable interest. Motivated by the importance of studies of quantum transport in rough nanowires, here we examine how colored surface roughness impacts the conductance of two-dimensional quantum waveguides, using direct scattering calculations based on the reaction matrix approach. The computational results are analyzed in connection with a theoretical relation between the localization length and the structure factor of correlated disorder. We also examine and discuss several cases that have not been treated theoretically or are beyond the validity regime of available theories. Results indicate that conductance properties of quantum wires are controllable via colored surface disorder.
