| 摘 要： | 考虑到无序层中的体杂质散射以及绝缘界面层的粗糙散射，运用Bogoliubov-de Gennes(BdG)方程和Blonder-Tinkham-Klapwijk(BTK)理论模型，计算正常金属-绝缘层-无序层-s波超导隧道结系统的微分电导、平均电流和散粒噪声功率，研究表明，无序层中的杂质散射和粗糙界面散射都能抑制系统的微分电导、平均电流和散粒噪声功率。

| Abstract: | Taking account of impurities scattering in disordered metal and rough interface scattering in insulator, and using theBogoliubov-de Gennes equations and the Blonder-Tinkham-Klapwijk model, we calculate the differential conductance, average current and shot noise powerin the normal metal-insulator-disordered metal-superconductor junctions. It is shown that the differential conductance, average current and shot noise powerare suppressed by the impurities and rough interface scattering. |
