Atomistic substrate relaxation effects in the band gaps of graphene on hexagonal boron nitride
Jiaqi An, Nicolas Leconte, Srivani Javvaji +2
We assess the impact of atomistic substrate lattice relaxation schemes in the primary band gap at charge neutrality and the secondary valence band gap of graphene on hexagonal boro…

Topological flat bands without magic angles in massive twisted bilayer graphenes
Srivani Javvaji, Jinhua Sun, Jeil Jung
Twisted bilayer graphene (TBG) hosts nearly flat bands with narrow bandwidths of a few meV at certain {\em magic} twist angles. Here we show that in twisted gapped Dirac material b…

Pressure Induced Compression of Flatbands in Twisted Bilayer Graphene
Bheema Lingam Chittari, Nicolas Leconte, Srivani Javvaji +1
We investigate the bandwidth compression due to out of plane pressure of the moire flatbands near charge neutrality in twisted bilayer graphene for a continuous range of small rota…
