Journal ArticleDOI
Spin-resolved Andreev levels and parity crossings in hybrid superconductor–semiconductor nanostructures
Eduardo J. H. Lee,Xiaocheng Jiang,Manuel Houzet,Ramón Aguado,Charles M. Lieber,Silvano De Franceschi +5 more
TL;DR: A direct measurement of the Zeeman effect on the Andreev levels of a semiconductor quantum dot with large electron g-factor, strongly coupled to a conventional superconductor with a large critical magnetic field allows spin degeneracy to be lifted without destroying superconductivity.
Journal ArticleDOI
Tunable supercurrent through semiconductor nanowires
Yong-Joo Doh,Jorden A. van Dam,Jorden A. van Dam,Aarnoud Laurens Roest,Aarnoud Laurens Roest,Erik P. A. M. Bakkers,Erik P. A. M. Bakkers,Leo P. Kouwenhoven,Leo P. Kouwenhoven,Silvano De Franceschi,Silvano De Franceschi +10 more
TL;DR: Nanoscale supercond conductor/semiconductor hybrid devices are assembled from indium arsenide semiconductor nanowires individually contacted by aluminum-based superconductor electrodes, which form superconducting weak links operating as mesoscopic Josephson junctions with electrically tunable coupling.
Journal ArticleDOI
Supercurrent reversal in quantum dots
Jorden A. van Dam,Yuli V. Nazarov,Erik P. A. M. Bakkers,Silvano De Franceschi,Silvano De Franceschi,Leo P. Kouwenhoven +5 more
TL;DR: It is demonstrated that the supercurrent reverses sign is added by adding a single electron spin to the quantum dot by means of local electrostatic gating, which depends on the character of the orbital wavefunctions.
Journal ArticleDOI
Orbital Kondo effect in carbon nanotubes
Pablo Jarillo-Herrero,Jing Kong,Jing Kong,Herre S. J. van der Zant,Cees Dekker,Leo P. Kouwenhoven,Silvano De Franceschi,Silvano De Franceschi +7 more
TL;DR: It is shown that the unique electronic structure of carbon nanotubes enables the observation of a purely orbital Kondo effect, and it is concluded that the orbital quantum number is conserved during tunnelling.
Journal ArticleDOI
Zero-bias anomaly in a nanowire quantum dot coupled to superconductors.
Eduardo J. H. Lee,Xiaocheng Jiang,Ramón Aguado,Georgios Katsaros,Charles M. Lieber,Silvano De Franceschi +5 more
TL;DR: This work ascribes the coexistence of a Kondo resonance and a superconducting gap to a significant density of intragap quasiparticle states, and the finite-bias subgap structures to tunneling through Shiba states, in relation to tunnel-spectroscopy experiments aiming at the observation of Majorana fermions in hybrid nanostructures.
