考虑界面粗糙散射 ,在Blonder Tinkham Klapwijk(BTK)理论框架下 ,通过求解Bogoliubov deGennes(BdG)方程 ,分别计算T =0K和有限温度下 ,dx2 -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 . In the framework of Blonder Tinkham Klapwijk (BTK) theory, the Bogoliubov deGennes (BdG) equation is considered to calculate the coherent states of the dx2-y2 + idxy mixed wave normal metal insulator superconductor junctions at T = 0K and finite temperature, respectively Quasiparticle transport coefficient and tunneling spectrum.The results show that the splitting of the conduction peak in the tunneling spectrum strongly depends on the strength of the dxy wave component, the crystal axis orientation of the superconductor and the interface roughness, while the increase of temperature can lower the conductance peak .
