Under random phase approximation, it shows that two branches of plasmon modes can be achieved via the conduction-band transitions due to the SOCs, which are different from the plasmons in a two-dimensional electron gas and graphene owing to the quasi-linear energy dispersion in single-layer MoS...
Single-layer MoS2 is an attractive semiconducting analogue of graphene that combines high mechanical flexibility with a large direct bandgap of 1.8 eV. On the other hand, bulk MoS2 is an indirect bandgap semiconductor similar to silicon, with a gap of 1.2 eV, and therefore deterministic preparation...
Suspended single-layer MoS2 devices We have fabricated and characterized suspended single-layer MoS2devices to investigate the substrate effect on the electrical properties of MoS2. The MoS2d... T Jin,J Kang,ES Kim,... - 《Journal of Applied Physics》...
transistors with room-temperature current on/off ratios of 1 × 108and ultralow standby power dissipation. Because monolayer MoS2has a direct bandgap16,18, it can be used to construct interband tunnel FETs19, which offer lower power consumption than classical transistors. Monolayer MoS2could also ...

Mechanical resonators are fabricated from freely suspended single-layer MoS2 . Their dynamics have been studied by optical interferometry. These resonators behave as membranes with resonance frequencies in between 10 and 30 MHz and quality factors in between 16 and 109. We also demonstrate clear signat...
Valley magnetization in single-layer MoS2 is demonstrated by breaking the three-fold rotational symmetry via uniaxial stress. The results are consistent with a theoretical model of valley magnetoelectricity driven by Berry curvature effects. The magnetoe
Low frequency electronic Noise in single-layer MoS2 transistors MoS2 and related metal dichalcogenides (MoSe2, WS2, WSe2) are layered two-dimensional materials that are promising for nanoelectronics and spintronics. For... QH Wang,K Kalantar-Zadeh,A Kis,... - 《Nature Nanotechnology》 被引量: ...
The use of single-layer MoS2 in light emitting devices requires innovative methods to enhance its low photoluminescence (PL) quantum yield. In this work, we report that single-layer MoS2 with a strong PL can be prepared by oxidizing bilayer MoS2 using UV-ozone oxidation. We show that as comp...
