| 520 | _ | _ | |a Semiconductor nanowires, fabricated by a bottom-up approach, are very promising as building blocks for future nanoscaled electronic devices. In addition, they are also very interesting objects for studying quantum phenomena. In recent years, the focus shifted partly towards more complex nanowire structures, i.e. radial and axial heterostructure nanowires, in order to tailor their electronic properties even better. We investigated GaAs/InAs core/shell nanowires, where the highly conductive InAs shell is wrapped around an insulating GaAs core. At low temperatures pronounced flux periodic magnetoconductance oscillations are observed. These very regular oscillations can be explained by the presence of circular closed-loop quantum states. The magnetoconductance oscillations could even be observed up to temperatures of 50K. By selective wet chemical etching, the GaAs core was removed, leaving a hollow InAs nanowire. Here, flux-periodic oscillations where observed as well. When the GaAs/InAs core/shell nanowire is contacted by two superconducting electrodes the carrier transport is governed by Andreev reflection. In this case the period in the magnetoconductance corresponds to half a flux quantum. |
