文摘The tunneling spectrum of an electron and a hole in metal superconductor-metal junctions is com- puted using the Blonder-Tinkham Klapwijk method. The incident and the outgoing currents finally balance each other by an interface charge inside the superconductor and metal junction. The present computation shows a more abundant structure compared to that on a metal superconductor junc- tion, such as the resonance at bias voltages above the energy gap of the superconductor. The density of the interface charge shows a quantum-like oscillation.
