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…
Plasmons in realistic graphene/hexagonal boron nitride moiré patterns
Andrea Tomadin, Marco Polini, Jeil Jung
Van der Waals heterostructures employing graphene and hexagonal boron nitride (hBN) crystals have emerged as a promising platform for plasmonics thanks to the tunability of their c…
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…
Wannier Pairs in the Superconducting Twisted Bilayer Graphene and Related Systems
Sujay Ray, Jeil Jung, Tanmoy Das
Unconventional superconductivity often arises from Cooper pairing between neighboring atomic sites, stipulating a characteristic pairing symmetry in the reciprocal space. The twist…
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…
