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 $_{g}^{1}$ , B $_{2 g}$ and A $_{g}^{2}$ of the orthorhombic phase show…

Emergence of a weak topological insulator from the Bi $_{x}$ Se $_{y}$ family and the observation of weak anti-localization

Kunjalata Majhi, Koushik Pal, Himanshu Lohani +7

The discovery of strong topological insulators led to enormous activity in condensed matter physics and the discovery of new types of topological materials. Bisumth based chalcogen…

Pressure-induced phase transition in Bi $_{2}$ Se $_{3}$ 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 $\sim$ 3 GPa exhibited by the A $_{2}$ B $_{3}$ -type 3D topological insulators is attributed to an electronic topological transition (E…
