Monolayer MoS2 was exfoliated by intercalation with lithium in 1986 [1]. The advantage of monolayer MoS2 complementary over graphene is the layer-dependent band-gap tunability. The band structure of graphene exhibits a linear dispersion and the charge carriers act as massless Dirac fermions [2]. ...

Band structure calculations for the two systems, on the other hand, show that the impurity states in the band gap shift towards the valence or conduction bands of monolayer MoS2, depending on the direction of the applied perpendicular electric field. Figure 5 Electric field effect. (a) ...
However, another band-structure calculation on similar material of monolayer MoS2 indicates the existence of a B-trionic peak next to the B-exitonic peak22. The identification of the B1 CP is not yet clear because it is dominated by the huge B2 CP. This needs to be investigated in more ...
Mechanically exfoliated monolayers of WS2, MoS2and their van der Waals heterostructure were fabricated on flexible substrate so that uniaxial tensile strain can be applied to the two-dimensional samples. The modification of the band structure under strain was investigated by micro-photoluminescence spectros...
Monolayer MoS2Recently, the nonlinear optical processes study on monolayer MoS2 has revealed the existence of a trigonal warping in the band structure which distorts the Fermi surface from a circle at low energies to a triangle at higher energies. Here we theoretically demonstrate that the trigonal...
Of particular significance is the revelation that the versatile vacancies can modulate the band structure of the monolayer MoS2 , leading to a decrease of the bandgap and an obvious n-doping effect. These results are confirmed by scanning tunneling spectroscopy data as well as first-principles ...
为了研究缺陷对单层MoS2的电子结构, 本文基于密度泛函理论框架下的第一性原理, 采用数值基组的方法计算了MoS2的Mo位缺陷、S位缺陷的能带结构和态密度.结果发现:Mo位缺陷、S位缺陷的MoS2的能带结构中的价带顶与导带底都在Q点, 为直接带隙材料; 其中Mo位缺陷体的禁带区域都出
