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…
1/f noise as a probe for investigating band structure in graphene
Atindra Nath Pal, Subhamoy Ghatak, Vidya Kochat +4
A distinctive feature of single layer graphene is the linearly dispersive energy bands, which in case of multilayer graphene become parabolic. Other than the quantum Hall effect, t…
