摘    要:用Bogoliubov-de Gennes方程来研究量子线/绝缘层/p波超导体结(q/I/p)中的准粒子输运过程,利用推广的Blonder,Tinkham和Klapwijk模型计算绝对零度和有限温度下q/I/p的一级谐波隧道谱.和量子线/绝缘层/d波超导体结的一级谐波隧道谱不同的是q/I/p的一级谐波隧道谱中存在零偏压电导峰.随着q/I/p中绝缘层的势垒散射增强,q/I/p的一级谐波隧道谱中零偏压电导峰变高.

关 键 词:量子线  p波超导体  隧道谱

Abstract:Using Bogoliubov-de Gennes equations,we study the quasiparticle transport in quantum-wire/insulator/p wave superconductor junction (q/I/p). In the framework of the Blonder-Tinkham-Klapwijk model,we calculate the tunneling conductance in q/I/p as a function of the bias voltage at zero temperature and finite temperature. Differently from the case in quantum-wire/insulator/d wave superconductor junctions,there are zero-bias conductance peaks in the single-mode case. With the barrier strength becoming strong,the zero-bias conductance is gradually enhanced.
Keywords:quantum-wire   p-wave superconductor   tunneling conductance
