| 摘 要： | 考虑界面粗糙散射,在Blonder-Tinkham-Klapwijk(BTK)理论框架下,通过求解Bogoliubov-de-Gennes(BdG)方程,分别计算T=0K和有限温度下,d(x2-y2)+idxy混合波正常金属绝缘层超导体结中的准粒子输运系数和隧道谱.研究表明:隧道谱中的电导峰的劈裂程度强烈地依赖于dxy波分量的强度、超导体的晶轴方位和界面粗糙强度,而温度的升高能压低电导峰.

| Abstract: | According to the Blonder-Tinkham-Klapwijk approach,we calculate the electron transport coefficients through a junction of a mixed d(x2-y2)+idxy wave superconductor and a normal metal with a rough interface. We investigate the effects of rough strength of the interface and the mixing of the two symmetries on electron tunneling.It is found that the tunneling spectrum depends strongly on the relative strength of the two components. The zero-bias conductance peak splits into two peaks due to the mixing. |
