The development of efficient thermal energy management devices such as thermoelectrics, barrier coatings, and thermal data-storage disks often relies on compounds that possess very…
Microscopic mechanism of unusual lattice thermal transport in TlInTe
Koushik Pal, Yi Xia, Chris Wolverton
We investigate the microscopic mechanism of ultralow lattice thermal conductivity () of TlInTe and its weak temperature dependence using a unified theory of lattice heat t…
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…
Emergence of a weak topological insulator from the BiSe 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…
