In this work, we present a systematic analysis, carried out in the framework of density-functional theory, on the influence of uniaxial strain on the electronic and optical properties of monolayer MoTe2. By spanning a 卤10% range of deformation along the armchair and zigzag...
Of special interest is MoTe_2, where the stable semiconducting 2H and metastable (semi)metallic 1T' phases have a rather small energy difference implying the low-energy cost of such a transition. In this work, using first-principles calculations, we demonstrate that there exists a previously ...

superior supercapacitor electrode material7. In addition, some monolayers were synthesized in 2H phase and others in 1T phase. As, MoS24, MoSe2and MoTe28were synthesized experimentally in 2H phase and PtS29, PtSe210and NiTe211in 1T phase. While the synthesis of 1T phase NiSe212and PtTe213...
Most importantly, the desirable type II band alignment can be found in Te/TMD vdWHs, which results in strong charge separation and enhanced sunlight absorption. Particularly, the proposed Te/WTe2 and Te/MoTe2 vdWH solar cells show the maximum power conversion efficiencies up to 22.5% and 20.1...
Quasiparticle band structures and optical properties of MoS2, MoSe2, MoTe2, WS2, and WSe2 monolayers are studied using the GW approximation in conjunction ... A Ramasubramaniam - 《Physical Review B Condensed Matter》 被引量: 501发表: 2012年 Optical signature of symmetry variations and spin-val...
We find that for all six species considered, including MoS, WS, SnS, VS, MoSeand MoTe, that compressive strain of up to 10% decreases the work function continuously by as much as 1.0eV. Large enough tensile strain is also found to decrease the work function, although in some cases we ...
