The effect of a magnetic field on the current-voltage characteristics of MoRe–Si(W)–MoRe heterostructures formed by superconducting banks (molybdenum-rhenium alloy) and a hybrid semiconducting tunnelling barrier (nanoscale silicon layer with tungsten nanoclusters) is investigated experimentally. A growth of the resistive region in the corresponding curves is observed and it is shown that this effect is a consequence of a modification in the weak localization of electrons in the disordered barrier under the influence of the applied magnetic field.
Key words: current-voltage characteristics, hybrid superconducting heterostructures, resonant-percolation one-dimensional transport, weak localization.
