Finite frequency Seebeck coefficient of metals: A memory function approach
Pankaj Bhalla, Pradeep Kumar, Nabyendu Das +2
We study the dynamical thermoelectric transport in metals subjected to the electron-impurity and the electron-phonon interactions using the memory function formalism. We introduce…
Iron Isotope Effect in SmFeAsO0.65 and SmFeAsO0.77H0.12 Superconductors: A Raman Study
Birender Singh, P. M. Shirage, A. Iyo +1
We report the inelastic light scattering studies on SmFeAsO0.65 and SmFeAsO0.77H0.12 with iron isotopes namely 54Fe and 57Fe. In both of these systems under investigation we observ…
Theory of the Dynamical Thermal conductivity of Metals
Pankaj Bhalla, Pradeep Kumar, Nabyendu Das +2
The Mori's projection method, known as memory function method is an important theoretical formalism to study various transport coefficients. In the present work, we calculate the d…
Structural phase transition and material properties of few-layer monochalcogenides
Mehrshad Mehboudi, Benjamin M. Fregoso, Yurong Yang +6
GeSe and SnSe monochalcogenide monolayers and bilayers undergo a two-dimensional phase transition from a rectangular unit cell to a square unit cell at a temperature well bel…
