Figure 5. Thermal conductivity in superlattice S2 composed of ordered crystalline layers intercalated with mass disordered alloy layers.
The two components κCP and κIP are plotted as functions of W. The mass ratio of the disordered alloy layer mB2/mB1 is (a) 2, (b) 4, and (c) 8. The values and
of the diffuse limits, together with those in the glass and the disordered alloy are indicated by lines.
