Journal ArticleDOI
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
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
Photonics and optoelectronics of 2D semiconductor transition metal dichalcogenides
Kin Fai Mak,Jie Shan +1 more
TL;DR: In this paper, the electronic and optical properties and the recent progress in applications of 2D semiconductor transition metal dichalcogenides with emphasis on strong excitonic effects, and spin- and valley-dependent properties are reviewed.
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.
Journal ArticleDOI
Observation of tightly bound trions in monolayer MoS2
TL;DR: In this paper, a quasi-particle composed of two electrons and a hole was identified in doped monolayer MoS2, which can be created with valley and spin polarized holes.
