TUNNELING SPECTRUM OF MIXED d(x2-y2)+idxy WAVE NORMAL METAL/INSULATOR/SUPERCONDUCTOR JUNCTIONS
|
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.
