Enhanced Raman and photoluminescence response in monolayer MoS due to laser healing of defects
Achintya Bera, D V S Muthu, A K Sood
Bound quasiparticles, negatively charged trions and neutral excitons, are associated with the direct optical transitions at the K-points of the Brillouin zone for monolayer MoS…
Pressure-dependent Semiconductor to Semimetal and Lifshitz transitions in 2H-MoTe: Raman and First-principles studies
Achintya Bera, Anjali Singh, D V S Muthu +2
High pressure Raman spectroscopy of bulk 2H-MoTe upto 29 GPa is shown to reveal two phase transitions (at 6 and 16.5 GPa), which are analyzed using first-principl…
Pressure-induced phase transition in BiSe at 3 GPa: electronic topological transition or not?
Achintya Bera, Koushik Pal, D V S Muthu +2
In recent years, a low pressure transition around P 3 GPa exhibited by the AB-type 3D topological insulators is attributed to an electronic topological transition (E…
Insights into vibrational and electronic properties of MoS using Raman, photoluminescence and transport studies
Achintya Bera, A. K. Sood
We review vibrational and electronic properties of single and a few layer MoS relevant to understand their resonant and non-resonant Raman scattering results. In particular, th…
Sharp Raman Anomalies and Broken Adiabaticity at a Pressure Induced Transition from Band to Topological Insulator in Sb2Se3
Achintya Bera, Koushik Pal, D. V. S. Muthu +4
The nontrivial electronic topology of a topological insulator is thus far known to display signatures in a robust metallic state at the surface. Here, we establish vibrational anom…
