Quantum Transport in a Superconductor-Semiconductor Mesoscopic System

Abstract

PACS: 73.30.+y; 73.40.Gk The quantum transport characteristics of a mesoscopic system are studied. Using the WKB method the current density was derived due to both, normal tunneling and Andreev reflection processes. The tunneling process was treated as a stochastic process, therefore, the energies of the tunneled electrons and the value of the Schottky barrier height at the S-Sm interface are determined by using a Monte-Carlo simulation technique. Numerical calculation of the current has been performed at different temperatures and bias voltage. The obtained results fit nicely with the experimental results in the literature. These results are very important for nanotechnology applications.

“…12,[20][21][22] Also, the Schottky barrier height, V b , is determined by using the Monte-Carlo simulation technique and its value was found to be ∼ 0.47 eV for the case Nb-GaAs based heterostructure interface. This value of V b was found to be in agreement with those found experimentally.…”

“…This value of V b was found to be in agreement with those found experimentally. 22,23 A periodic oscillation of conductance, G, with the gate voltage, V g , is shown in Fig. 1 at different temperatures and magnetic field.…”

Electron Transport and Josephson-Conductance in Mesoscopic Systems

“…Mesoscopic physics and superconductivity are intimately related through the Bogoliubov-de Gennes (BdG) equations. [1][2][3] It should therefore not be surprising that the wave interference of quasiparticles controls both the current-phase relationship of a Josephson junction [4][5][6] and the current-voltage characteristic of a normal-metalsuperconductor tunnel junction. 7−10 Both the Josephson Effect and Giaever tunneling are mesoscopic phenomena.…”
