Accurate Gap Determination in Monolayer and Bilayer Graphene/h-BN Moire Superlattices
Hakseong Kim, Nicolas Leconte, Bheema L. Chittari +5
High mobility single and few-layer graphene sheets are in many ways attractive as nanoelectronic circuit hosts but lack energy gaps, which are essential to the operation of field-e…
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…
Gate-Tunable Topological Flat Bands in Trilayer Graphene-Boron Nitride Moiré Superlattices
Bheema Lingam Chittari, Guorui Chen, Yuanbo Zhang +2
We investigate the electronic structure of the flat bands induced by moiré superlattices and electric fields in nearly aligned ABC trilayer graphene-boron nitride interfaces where…
Evidence of Gate-Tunable Mott Insulator in Trilayer Graphene-Boron Nitride Moiré Superlattice
Guorui Chen, Lili Jiang, Shuang Wu +9
Mott insulator plays a central role in strongly correlated physics, where the repulsive Coulomb interaction dominates over the electron kinetic energy and leads to insulating state…
