Low-Defect Quantum Dot Lasers Directly Grown on Silicon Exhibiting Low Threshold Current and High Output Power at Elevated Temperatures
Konstantinos Papatryfonos, Jean-Christophe Girard, Mingchu Tang +6
The direct growth of III-V materials on silicon is a key enabler for developing monolithically integrated lasers, offering substantial potential for ultra-dense photonic integratio…
Hydrogenic Spin-Valley states of the Bromine donor in 2H-MoTe
Valeria Sheina, Guillaume Lang, Vasily Stolyarov +14
In semiconductors, the identification of doping atomic elements allowing to encode a qubit within spin states is of intense interest for quantum technologies. In transition metal d…
STM observation of the hinge-states of bismuth nanocrystals
Tianzhen Zhang, Valeria Sheina, Sergio Vlaic +6
The recent application of topological quantum chemistry to rhombohedral bismuth established the non-trivial band structure of this material. This is a 2order topological ins…
Atomic scale visualization of the p-d hybridization in III-V semiconductors doped with transition metal impurities
K. Badiane, G. Rodary, M. Amato +4
p-d hybridization of transition metal impurities in a semiconductor host is the mechanism that couples valence-band electrons and localized spins. We use scanning tunneling microsc…
Quantum confinement effects in Pb Nanocrystals grown on InAs
Tianzhen Zhang, Sergio Vlaic, Stéphane Pons +9
In the recent work of Ref.\cite{Vlaic2017-bs}, it has been shown that Pb nanocrystals grown on the electron accumulation layer at the (110) surface of InAs are in the regime of Cou…
Superconducting parity effect across the Anderson limit
Sergio Vlaic, Stéphane Pons, Tianzhen Zhang +7
How small superconductors can be? For isolated nanoparticles subject to quantum size effects, P.W. Anderson conjectured in 1959 that superconductivity could only exist when the ele…
Epitaxial Graphene Nanoribbons on Bunched Steps of a 6H-SiC(0001) Substrate: Aromatic Ring Pattern and Van Hove Singularities
M. Ridene, T. Wassmann, E. Pallecchi +3
We report scanning tunneling microscopy and spectroscopy investigation of graphene nanoribbons grown on an array of bunched steps of a 6H-SiC(0001) substrate. Our scanning tunnelin…
