Thermal conductivity of free-standing silicon nanowire using Raman spectroscopy

Sandhyarani Sahoo, Sameer Kumar Mallik, Mousam Charan Sahu +4

Low dimensional systems, nanowires, in particular, have exhibited excellent optical and electronic properties. Understanding the thermal properties in semiconductor nanowires is ve…

Raman signatures of pressure induced electronic topological and structural transitions in Bi2Te3

Gopal K. Pradhan, Achintya Bera, Pradeep Kumar +2

We report Raman signatures of electronic topological transition (ETT) at 3.6 GPa and rhombohedral (α-Bi2Te3) to monoclinic (β-Bi2Te3) structural transition at ~ 8 GPa. At the onset…

Elastic and structural instability of cubic Sn3N4 and C3N4 under pressure

Gopal K. Pradhan, Anil Kumar, Umesh V. Waghmare +2

We use in-situ high pressure angle dispersive x-ray diffraction measurements to determine the equation of state of cubic tin nitride Sn3N4 under pressure up to about 26 GPa. While…

Pressure-induced phonon-freezing in the ZnBeSe alloy: a study via the percolation mesoscope

Gopal K. Pradhan, Chandrabhas Narayana, Olivier Pages +8

We use the 1-bond -> 2-phonon percolation doublet of zincblende alloys as a mesoscope for an unusual insight into their phonon behavior under pressure. We focus on (Zn,Be)Se and sh…
