Magneto transport of pressure induced flatbands in large angle twisted bilayer graphene
Ayan Mondal, Priyanka Sinha, Bheema Lingam Chittari
Twisted bilayer graphene (TBG) exhibits flat electronic bands at the so-called magic angle (), leading to strong electron correlations and emergent quantum phases s…

Strain induced tunable band gap and optical properties of graphene on hexagonal boron nitride
Priyanka Sinha, Prasanta K. Panigrahi, Bheemalingam Chittari
In this study, we highlight the potential of strain engineering in graphene/hBN (hexagonal Boron nitride) 2D heterostructures, enabling their use as wide-range light absorbers with…

Magnetotransport properties of a twisted bilayer graphene in the presence of external electric and magnetic field
Priyanka Sinha, Ayan Mondal, Simão Meneses João +1
We extensively investigate the electronic and transport properties of a twisted bilayer graphene when subjected to both an external perpendicular electric field and a magnetic fiel…
