--- res: bibo_abstract: - The epitaxial growth of germanium on silicon leads to the self-assembly of SiGe nanocrystals by a process that allows the size, composition and position of the nanocrystals to be controlled. This level of control, combined with an inherent compatibility with silicon technology, could prove useful in nanoelectronic applications. Here, we report the confinement of holes in quantum-dot devices made by directly contacting individual SiGe nanocrystals with aluminium electrodes, and the production of hybrid superconductor- semiconductor devices, such as resonant supercurrent transistors, when the quantum dot is strongly coupled to the electrodes. Charge transport measurements on weakly coupled quantum dots reveal discrete energy spectra, with the confined hole states displaying anisotropic gyromagnetic factors and strong spin-orbit coupling with pronounced dependences on gate voltage and magnetic field.@eng bibo_authorlist: - foaf_Person: foaf_givenName: Georgios foaf_name: Georgios Katsaros foaf_surname: Katsaros foaf_workInfoHomepage: http://www.librecat.org/personId=38DB5788-F248-11E8-B48F-1D18A9856A87 - foaf_Person: foaf_givenName: Panayotis foaf_name: Spathis, Panayotis N foaf_surname: Spathis - foaf_Person: foaf_givenName: Mathieu foaf_name: Stoffel, Mathieu foaf_surname: Stoffel - foaf_Person: foaf_givenName: Frank foaf_name: Fournel, Frank foaf_surname: Fournel - foaf_Person: foaf_givenName: Massimo foaf_name: Mongillo, Massimo foaf_surname: Mongillo - foaf_Person: foaf_givenName: Vincent foaf_name: Bouchiat, Vincent foaf_surname: Bouchiat - foaf_Person: foaf_givenName: François foaf_name: Lefloch, François foaf_surname: Lefloch - foaf_Person: foaf_givenName: Armando foaf_name: Rastelli, Armando foaf_surname: Rastelli - foaf_Person: foaf_givenName: Oliver foaf_name: Schmidt, Oliver G foaf_surname: Schmidt - foaf_Person: foaf_givenName: Silvano foaf_name: De Franceschi, Silvano foaf_surname: De Franceschi bibo_doi: 10.1038/nnano.2010.84 bibo_issue: '6' bibo_volume: 5 dct_date: 2010^xs_gYear dct_publisher: Nature Publishing Group@ dct_title: Hybrid superconductor-semiconductor devices made from self-assembled SiGe nanocrystals on silicon@ ...
