Strain-induced direct–indirect bandgap transition and phonon modulation in monolayer WS2

TL;DR: In this article, Liu et al. employed in situ strain photoluminescence (PL) and Raman spectroscopy to exploit the evolutions of the electronic band structure and lattice vibrational responses of chemical vapor deposition (CVD)-grown monolayer tungsten disulphide (WS2) under uniaxial tensile strain.
Journal ArticleDOI

Thermal conductivity determination of suspended mono- and bilayer WS2 by Raman spectroscopy

TL;DR: In this paper, the thermal conductivities of monolayer (1L) and bilayer (2L) WS2 grown by chemical vapor deposition (CVD), which are determined by use of temperature and excitation dependences of E� 2g� 1 Skydragon and A1g Raman modes, were extracted.
Journal ArticleDOI

Chemically Driven Tunable Light Emission of Charged and Neutral Excitons in Monolayer WS2

TL;DR: The molecular adsorption can modulate the light emission and electrical properties of 1L WS2 and open up many opportunities to manipulate the electrical and optical properties of two-dimensional TMDs, particularly important for developing optoelectronic devices for chemical and biochemical sensing applications.
Journal ArticleDOI

Electrically Tunable Valley-Light Emitting Diode (vLED) Based on CVD-Grown Monolayer WS2

TL;DR: The first demonstration of electrically tunable chiral EL from CVD-grown monolayer WS2 by constructing a p-i-n heterojunction is reported, which reaches as high as 81% and can be effectively modulated by forward current.
Journal ArticleDOI

Mechanism of charge transfer and its impacts on Fermi-level pinning for gas molecules adsorbed on monolayer WS2.

TL;DR: The proposed mechanism governing Fermi-level pinning is applicable to the systems of adsorbates on recently developed two-dimensional materials, such as graphene and transition metal dichalcogenides.
