Doping mechanisms in graphene-MoS2 hybrids [PDF]

Applied Physics Letters, 2013
We present a joint theoretical and experimental investigation of charge doping and electronic potential landscapes in hybrid structures composed of graphene and semiconducting single layer molybdenum disulfide (MoS2). From first-principles simulations, we find electron doping of graphene due to the presence of rhenium impurities in MoS2.

Strain engineering in monolayer WS2, MoS2, and the WS2/MoS2 heterostructure [PDF]

Applied Physics Letters, 2016
Mechanically exfoliated monolayers of WS2, MoS2 and 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 spectroscopy at room temperature as well as by first ...
