Strain-induced modulation of Dirac cones and van Hove singularities in twisted graphene bilayer
Viet Hung Nguyen, Philippe Dollfus
By means of atomistic tight-binding calculations, we investigate the effects of uniaxial strain on the electronic bandstructure of twisted graphene bilayer. We find that the bandst…
Strain-induced conduction gap in vertical devices made of twisted graphene layers
Viet Hung Nguyen, Huy-Viet Nguyen, Jerome Saint Martin +1
We investigate the effects of uniaxial strain on the transport properties of vertical devices made of two twisted graphene layers, which partially overlap each other. We find that…
Enhanced thermoelectric figure of merit in vertical graphene junctions
V. Hung Nguyen, M. Chung Nguyen, Huy-Viet Nguyen +2
In this work, we investigate thermoelectric properties of junctions consisting of two partially overlapped graphene sheets coupled to each other in the cross-plane direction. It is…
Conduction gap in graphene strain junctions: direction dependence
Mai Chung Nguyen, Viet Hung Nguyen, Huy-Viet Nguyen +1
It has been shown in a recent study [Nguyen et al., Nanotechnol. \textbf{25}, 165201 (2014)] that unstrained/strained graphene junctions are promising candidates to improve the per…
