Influence of quantum confinement on the electronic structure of the transition metal sulfideTS2

Open access

Abstract

Bulk MoS${}_{2}$, a prototypical layered transition-metal dichalcogenide, is an indirect band gap semiconductor. Reducing its slab thickness to a monolayer, MoS${}_{2}$ undergoes a transition to the direct band semiconductor. We support this experimental observation by first-principle calculations and show that quantum confinement in layered $d$-electron dichalcogenides results in tuning the electronic structure. We further studied the properties of related $T$S${}_{2}$ nanolayers ($T=$ W, Nb, Re) and show that the isotopological WS${}_{2}$ exhibits similar electronic properties, while NbS${}_{2}$ and ReS${}_{2}$ remain metallic independent of the slab thickness.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
