Pressure Dependence of Ultrafast Carrier Dynamics in Excitonic Insulator TaNiSe
Vikas Arora, Victor S Muthu, Arijit Sinha +3
An excitonic insulator (EI) phase is a consequence of collective many-body effects where an optical band gap is formed by the condensation of electron-hole pairs or excitons. We re…
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…
Anomalous temperature dependence of optical and acoustic phonons in BiSe arising from stacking faults
Gyan Prakash, Koushik Pal, U. V. Waghmare +1
The class of layered 3D-topological insulators have shown intriguingly anomalous temperature dependence in their thermal expansion coefficients. It was proposed that stacking fault…
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…
