Abstract
This simulation tool solves simple 1D phonon transport problems by the atomistic Green's function (AGF) method. A phonon transmission function is derived from Green's functions and, using the transmission function, the thermal conductance integral in Landauer form is computed. Within the theoretical framework of the AGF, the required inputs to calculate conductance are the masses of atoms and an appropriate interatomic potential. Homogeneous and heterogeneous atomic chains can be simulated.
