A band-structure calculation of MoSe2 anticipated another transition in the B-excitonic peak, interpreting it as the first excited state of the A exciton23. Excited exciton states are observed in monolayer WS237, but have not yet been reported for monolayer MoSe2. However, another band-...
MoSe2grain boundaryhot water vaporsingle crystalBeyond graphene, two-dimensional (2D) transition metal dichalcogenides (TMDs) have attracted significant attention owing to their potential in next-generation nanoelectronics and optoelectronics. Nevertheless, grain boundaries are ubiquitous in large-area as-...

Weak or medium adsorption is found between ML MoSe2 and the Al, Ag, and Pt surfaces with the band structure of ML MoSe2 preserved, while strong adsorption is found between ML MoSe2 and the Ni, Ti, and Cr surfaces with the band structure of ML MoSe2 destroyed. The two methods give si...

Accurate prediction of band gap for new emerging materials is highly desirable for the exploration of potential applications. The band gaps of bulk and monolayer TMDs (MoS 2 , MoSe 2 , WS 2 , and WSe 2 ) are calculated with the recently proposed by us GVJ-2e method, which is implemented...
The gate dependence of XI is consistent with that expected for the interlayer exciton, which maintains a dipole pointing from MoSe2 to WSe2 (Fig. 3a). At negative Vg, the electric ?eld reduces the relative band-offset between the MoSe2 and WSe2 in device 2, increasing the energy ...
Various semiconducting 2D materials have been studied, including transition metal dichalcogenides (TMDs) such as molybdenum disulfide (MoS2), molybdenum diselenide (MoSe2), tungsten diselenide (WSe2), which are likely to bring breakthroughs in future electronic and optoelectronic devices [6], [7], [...
1b. As expected, the shape of the band structure is almost identical to the band structures of monolayer MoS2, MoSe2, WSe2 and WTe2 found in previous works32. However, unlike Mo- and W-based materials which are insulating intrinsically, an Nb atom has one less d-electron in the outer...
band gap. The same has been found for a number of 2D materials that have been extensively studied in the last years. Results for MoS2, MoSe2, MoTe2, WS2, WSe2, BN, and phosphorene are summarized in the Supplementary Information. In the extreme cases of MoS2, WS2, WSe2, and BN, the...
