Moire-Engineered Excitonic Landscape and Phonon-Mediated Recombination in Twisted WSe2 Bilayers
Memansa Thapa, Aksa Thomas, Jayalekshmi U. J. +7
We report light emission from the moire superlattice of a twisted bilayer of tungsten diselenide (WSe2/WSe2) encapsulated in insulating hexagonal boron nitride (hBN). The low-tempe…
Emergence of spin-phonon coupling in a Gd-doped YCoMnO double perovskite oxide: a combined experimental and ab-initio study
Anasua Khan, Debdatta Banerjee, Divya Rawat +4
We present Raman spectroscopy results backed by first-principles calculations and investigate the nature of possible spin-phonon coupling (SPC) in a Gd-doped YCoMnO (YGCMO)…
Lattice Mismatch Driven In Plane Strain Engineering for Enhanced Upper Critical Fields in Mo2N Superconducting Thin Films
Aditya Singh, Divya Rawat, Victor Hjort +5
Transition metal nitrides are a fascinating class of hard coating material that provide an excellent platform for investigating superconductivity and fundamental electron phonon in…
Electron-phonon interactions and tensor analysis in topological insulator bismuth telluride using angle resolved polarized Raman spectroscopy
Aditya Singh, Anna Elsukova, Divya Rawat +6
We report on the angle-resolved polarized Raman spectroscopy and estimation of the Raman tensor elements using both classical and quantum treatments to analyse the polarized Raman…
