Lattice thermal conduction across the disordered interfaces in multilayered
materials has been studied. The model consists of an array of slabs of sca
ttering centers (mass defects) embedded in a host material. The layered dis
tribution of the mass defects can be characterized by the structure factor
in the scattering probability due to the slabs. We assume that the physical
arrangement of the scattering centers within a slab is quenched disorder a
nd is approximately described by the structure factor of a homogeneous liqu
id interacting via hard sphere pair potentials. By varying the packing fi f
raction of the scattering centers from low density to high density, the cal
culated thermal conductivity exhibits the minimum which reflects the local
structural organization of the scattering centers. The relation to thermoel
ectric energy conversion has also been discussed.
