We detect electroluminescence in single layer molybdenum disulfide (MoS2) field-effect transistors built on transparent glass substrates. By comparing the absorption, photoluminescence, and electroluminescence of the same MoS2 layer, we find that they all involve the same excited state at 1.8 eV. The electroluminescence has pronounced threshold behavior and is localized at the contacts. The results show that single layer MoS2, a direct band gap semiconductor, could be promising for novel… Expand

Defect passivation induced strong photoluminescence enhancement of rhombic monolayer MoS2.
TLDR
Density functional theory (DFT) calculations show that passivation of defects in MoS2 removes trapping gap states, which may finally result in PL enhancement, and show that rhombic monolayer MoS 2 with PL intensity 8 times stronger than those of chemical vapour deposition (CVD) can be prepared by using CVD.
