Zero point motion and direct/indirect bandgap crossover in layered transition-metal dichalcogenides

L. Ortenzi, L. Pietronero, E. Cappelluti

Two-dimensional transition-metal dichalcogendes $M{X}_2$ (es. MoS${}_2$, WS${}_2$, MoSe${}_2$, \ldots) are among the most promising materials for bandgap engineering. Widely studied in the…
