Conductance Suppression in Normal Metal-superconductor Mesoscopic Strucutres
Using a scattering matrix approach and quasiclassical Green's function technique, we calculate the conductance of the S/N system (see Fig.1). We establish that the difference between the su-perconducting and normal state conductance (δG = Gs − Gn) is negative for large S/N interface resistances (R S/N) and changes sign with decreasing R S/N. The comparision of the results obtained with experime...
متن کاملTunneling conductance in normal metal - triplet superconductor junction
We calculate the tunneling conductance spectra of a normal metal / insulator / triplet superconductor from the reflection amplitudes using the Blonder-Tinkham-Klapwijk (BTK) formula. For the triplet superconductor we assume one special p-wave order parameter having line nodes and two two dimensional f -wave order parameters with line nodes breaking the time-reversal symmetry. Also we examine no...
متن کاملEffect of a Magnetic Field on Tunneling Conductance in Normal Metal d-Wave Superconductor Interfaces
Through the analytic solutions of the Bogoliubov de Gennes (BdG) equations the effect of a static and homogeneous magnetic field applied parallel to the interface of an NIS (N: Normal metal, S: superconductor and I: Insulator) junction on the differential conductance is calculated. For a dxy symmetry we obtain zero bias conductance peak that can be split by a magnetic field. The shift of the ze...
متن کاملRole of critical current on the point-contact Andreev reflection spectra between a normal metal and a superconductor
The point-contact spectrum between a normal metal and a superconductor often shows unexpected sharp dips in the conductance at voltage values larger than the superconducting energy gap. These dips are not predicted in the Blonder-Tinkham-Klapwijk ~BTK! theory, commonly used to analyze these contacts. We present here a systematic study of these dips in a variety of contacts between different com...
متن کاملSize effects in the density of states in normal-metal-superconductor and superconductor-normal-metal-superconductor junctions.
The quasiparticle local density of states ~LDOS! is studied in clean normal-metal–superconductor ~NS! and superconductor–normal-metal–superconductor ~SNS! junctions with increasing transverse size, from quasione-dimensional to three-dimensional. It is shown that finite transverse dimensions are related to pronounced effects in the LDOS, such as fast oscillations superimposed on the quasiparticl...
