摘要
Resonant transport in a hybrid semi conductor-superconductor microstructure grown by MBE on GaAs in presented. This structure experimentally realizes the prototype system originally proposed by de Gennes and Saint-James in 1963 in all-metal structures. A low temperature single peak superimposed to the characteristic Andreev-dominated subgap conductance represents the mark of such resonant behavior. Random matrix theory of quantum transport was employed in order to analyze the observed magnetotransport properties and ballistic effects were included by directly solving the Bogoliubov-de Gennes equations.
