Electric field exfoliation and high-T superconductivity in field-effect hole-doped hydrogenated diamond (111)
Davide Romanin, Thibault Sohier, Dario Daghero +3
We investigate the possible occurrence of field-effect induced superconductivity in the hydrogenated diamond surface by first-principles calculations. By computing the band…
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…
Enhanced electron-phonon interaction in multi-valley materials
Evgeniy Ponomarev, Thibault Sohier, Marco Gibertini +4
Through a combined theoretical and experimental effort, we uncover a yet unidentified mechanism that strengthens considerably electron-phonon coupling in materials where electron a…
