Probing interlayer interactions and commensurate-incommensurate transition in twisted bilayer graphene through Raman spectroscopy
Vineet Pandey, Subhendu Mishra, Nikhilesh Maity +8
Twisted 2D layered materials have garnered a lot of attention recently as a class of 2D materials whose interlayer interactions and electronic properties are dictated by the relati…
Atomically Thin Yellow Pearl: An Impetus for Thermal Nonlinear Optical Effect Assisted Continuous Wave Random Lasing
N. Mandal, A. Pramanik, A. Dey +7
Above cryogenic temperatures, random laser (RL) emission under continuous wave (CW) optical pumping is often challenging for materials having plenty of lattice defects. Thus, inten…
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…
Quaternary two-dimensional (2D) transition metal dichalcogenides (TMDs) with tunable bandgap
Sandhya Susarla, Alex Kutana, Jordan A. Hachtel +7
Alloying/doping in two-dimensional material has been important due to wide range band gap tunability. Increasing the number of components would increase the degree of freedom which…
Atomically thin gallium layers from solid-melt exfoliation
V. Kochat, A. Samanta, Y. Zhang +8
Among the large number of promising two-dimensional (2D) atomic layer crystals, true metallic layers are rare. Through combined theoretical and experimental approaches, we report o…
Fermi-edge transmission resonance in graphene driven by a single Coulomb impurity
Paritosh Karnatak, Srijit Goswami, Vidya Kochat +2
The interaction between the Fermi sea of conduction electrons and a non-adiabatic attractive impurity potential can lead to a power-law divergence in the tunneling probability of c…
Direct observation of valley-hybridization and universal symmetry of graphene with mesoscopic conductance fluctuations
Atindra Nath Pal, Vidya Kochat, Arindam Ghosh
In graphene, the valleys represent spin-like quantities and can act as a physical resource in valley-based electronics to novel quantum computation schemes. Here we demonstrate a d…
