Raman anomalies as signatures of pressure induced electronic topological and structural transitions in black phosphorus: Experiments and Theory
Satyendra Nath Gupta, Anjali Singh, Koushik Pal +4
We report high pressure Raman experiments of Black phosphorus up to 24 GPa. The line widths of first order Raman modes A, B and A of the orthorhombic phase show…
Metallic monoclinic phase in VO induced by electrochemical gating: in-situ Raman study
Satyendra Nath Gupta, Anand Pal, D. V. S. Muthu +2
We report in-situ Raman scattering studies of electrochemically top gated VO thin film to address metal-insulator transition (MIT) under gating. The room temperature monoclinic…
Spin liquid like Raman signatures in hyperkagome iridate NaIrO
Satyendra Nath Gupta, P. V. Sriluckshmy, Ashiwini Balodhi +5
Combining Raman scattering measurements with mean field calculations of the Raman response we show that Kitaev-like magnetic exchange is dominant in the hyperkagome iridate NaI…
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…
