Tuning exciton complexes in twisted bilayer WSe2 at intermediate misorientation
Rahul Debnath, Shaili Sett, Sudipta Kundu +5
Twist angle modifies the band alignment, screening, and interlayer (IL) coupling in twisted bilayers (tBLs) of transition metal dichalcogenides. Intermediate misorientation (twist…
Quantum Hall interferometry in triangular domains of marginally twisted bilayer graphene
Phanibhusan S. Mahapatra, Manjari Garg, Bhaskar Ghawri +5
Quantum Hall (QH) interferometry provides an archetypal platform for the experimental realization of braiding statistics of fractional QH states. However, the complexity of observi…
Emergence of broken-symmetry states at half-integer band fillings in twisted bilayer graphene
Saisab Bhowmik, Bhaskar Ghawri, Nicolas Leconte +9
The dominance of Coulomb interactions over kinetic energy of electrons in narrow, non-trivial moiré bands of magic-angle twisted bilayer graphene (TBG) gives rise to a variety of c…
Defects-Assisted Piezoelectric Response in Liquid Exfoliated MoS2 Nanosheets
Jyoti Shakya, Gayathri H N, Arindam Ghosh
We report piezoelectric response in liquid phase exfoliated MoS2 nanosheets with desired structure and morphology. The piezoelectric effect in liquid phase exfoliated few layers of…
Spontaneous time reversal symmetry breaking at individual grain boundaries in graphene
Kimberly Hsieh, Vidya Kochat, Tathagata Biswas +8
Graphene grain boundaries have attracted interest for their ability to host nearly dispersionless electronic bands and magnetic instabilities. Here, we employ quantum transport and…
Excess entropy and breakdown of semiclassical description of thermoelectricity in twisted bilayer graphene close to half filling
Bhaskar Ghawri, Phanibhusan S. Mahapatra, Shinjan Mandal +9
In moiré systems with twisted bilayer graphene (tBLG), the amplification of Coulomb correlation effects at low twist angles () is a result of nearly flat low-energy electronic b…
