The minimum limit to the thermal conductivity of disordered, layered solids is studied by accounting for minimum scattering times and velocities from oscillations of atoms bound by different interatomic forces. The model developed in this work allows for quantification of changes in the lower limit to thermal conductivity in heavily disordered solids due to force differences arising from planar interfaces. This model sets a lower limit to recent data of thermal conductivity of WSe2 layered films, the data from which were below the lower limits predicted by previous models.
