Thermal conductivity of Bi\(_2\)Se\(_3\) from bulk to thin films: theory and experiment

By Lorenzo Paulatto and others
We calculate the lattice-driven in-plane \((\kappa_{\parallel})\) and out-of-plane \((\kappa_{\perp})\) thermal conductivities of Bi\(_2\)Se\(_3\) bulk, and of films of different thicknesses, using the Boltzmann equation with phonon scattering times obtained from anharmonic third order density functional perturbation theory. We compare our results for the lattice component of the thermal conductivity with... Show more
