Thermal conductivity of Bi${}_2$Se${}_3$ from bulk to thin films: theory and experiment

Lorenzo Paulatto, Danièle Fournier, Massimiliano Marangolo +3

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…
