Double Fe-impurity charge state in the topological insulator BiSe
V. S. Stolyarov, S. V. Remizov, D. S. Shapiro +10
The influence of individual impurities of Fe on the electronic properties of topological insulator BiSe is studied by Scanning Tunneling Microscopy. The microscope tip is u…
Emerging one-dimensionality from self-organization of electrons in NbSe
M. A. Valbuena, P. Chudzinski, S. Pons +9
Materials where the electron filling is close to commensurate filling provide one of the great challenges in materials science. Several proposals of unconventional orderings, where…
Silicon surface with giant spin-splitting
I. Gierz, T. Suzuki, E. Frantzeskakis +7
We demonstrate the induction of a giant Rashba-type spin-splitting on a semiconducting substrate by means of a Bi trimer adlayer on a Si(111) wafer. The in-plane inversion symmetry…
Remarkable effects of disorder on superconductivity of single atomic layers of lead on silicon
C. Brun, T. Cren, V. Cherkez +8
In bulk materials superconductivity is remarkably robust with respect to non-magnetic disorder. In the two-dimensional limit however, the quantum condensate suffers from the effect…
Selective band engineering of Bi/Si(111) by boron segregation
E. Barre, J. Villalobos-Castro, T. Pierron +4
Atomically thin layers of metals deposited on semiconductors display a variety of physical properties such as superconductivity, charge density waves, topological phases, strong sp…
