Pressure-induced Lifshitz transition in NbP: Raman, x-ray diffraction, electrical transport and density functional theory
Satyendra Nath Gupta, Anjali Singh, Koushik Pal +8
We report high pressure Raman, synchrotron x-ray diffraction and electrical transport studies on Weyl semimetals NbP and TaP along with first-principles density functional theoreti…

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…
