Abundance of topological order in exfoliable two-dimensional insulators
Antimo Marrazzo, Marco Gibertini, Davide Campi +2
Quantum spin Hall insulators are a class of two-dimensional materials with a finite electronic band gap in the bulk and gapless helical edge states. In the presence of time-reversa…
THz Surface Modes and Electron-Phonon Coupling in BiSe(111)
Adrian Ruckhofer, Davide Campi, Martin Bremholm +5
We present a combined experimental and theoretical study of the surface vibrational modes of the topological insulator (TI) BiSe with particular emphasis on the low-energy…
Valley-engineering mobilities in two-dimensional materials
Thibault Sohier, Marco Gibertini, Davide Campi +2
Two-dimensional materials are emerging as a promising platform for ultrathin channels in field-effect transistors. To this aim, novel high-mobility semiconductors need to be found…
