Insight into the electronic structure of semiconducting epsilon-GaSe and epsilon-InSe

Marco Grioni, Helmuth Berger, Alberto Crepaldi, Daniela Pacilè

Metal monochalcogenides (MX) have recently been rediscovered as two-dimensional materials with electronic properties highly dependent on the number of layers. Although some intriguing properties appear in the few-layer regime, the carrier mobility of MX co ...

Spin-resolved band structure of a densely packed Pb monolayer on Si(111)

Jan Hugo Dil, Stefan Peter Muff, Mauro Fanciulli

Monolayer structures of Pb on Si(111) attracted recently considerable interest as superconductivity was found in these truly two-dimensional (2D) structures. In this study, we analyzed the electronic surface band structure of the so-called striped incommen ...
