Trapping the carrier in the spin-locked MoS2 atomic valley by absorption of chiral L-cysteine
Susmita Bhattacharya
This work, demonstrate enhanced valley contrasting spin-momentum locked chiral states at van der Waal interface of chiral L-cysteine and mono-atomically thin MoS2 placed at Si/SiO2…
Thickness dependent transition from the 1T to Weyl semimetal phase in ultrathin MoTe: Electrical transport, Noise and Raman studies
Manabendra Kuiri, Subhadip Das, D. V. S. Muthu +2
Bulk 1T-MoTe shows a structural phase transition from 1T to Weyl semimetallic (WSM) phase at 240 K. This phase transition and transport prope…
Symmetry induced phonon renormalization in few layers of 2H-MoTe transistors: Raman and first-principles studies
Subhadip Das, Koyendrila Debnath, Biswanath Chakraborty +5
Understanding of electron-phonon coupling (EPC) in two dimensional (2D) materials manifesting as phonon renormalization is essential to their possible applications in nanoelectroni…
Electron-Hole Asymmetry in the Electron-phonon Coupling in Top-gated Phosphorene Transistor
Biswanath Chakraborty, Satyendra Nath Gupta, Anjali Singh +6
Using in-situ Raman scattering from phosphorene channel in an electrochemically top-gated field effect transistor, we show that its phonons with A symmetry depend much more str…
