Atomically thin MoS2: a new direct-gap semiconductor

TL;DR: The electronic properties of ultrathin crystals of molybdenum disulfide consisting of N=1,2,…,6 S-Mo-S monolayers have been investigated by optical spectroscopy and the effect of quantum confinement on the material's electronic structure is traced.
Journal ArticleDOI

Anomalous lattice vibrations of single- and few-layer MoS2.

TL;DR: This work exemplifies the evolution of structural parameters in layered materials in changing from the three-dimensional to the two-dimensional regime by characterized by Raman spectroscopy.
Journal ArticleDOI

Control of valley polarization in monolayer MoS2 by optical helicity

TL;DR: It is demonstrated that optical pumping with circularly polarized light can achieve complete dynamic valley polarization in monolayer MoS(2) (refs 11, 12), a two-dimensional non-centrosymmetric crystal with direct energy gaps at two valleys.
Journal ArticleDOI

Tightly bound trions in monolayer MoS2

TL;DR: The spectroscopic identification in a monolayer MoS(2) field-effect transistor of tightly bound negative trions, a quasiparticle composed of two electrons and a hole is reported, which has no analogue in conventional semiconductors.
