(Color online) Schematic representation of the virtual crystal interface accompanied with associated heat resistance circuit. The interface region is replaced with a homogenized virtual crystal across which the phonon transmission coefficients are calculated, leading to TBC predictions.

(Color online) Thermal boundary conductance of a interface as a function of Si content. The model shows a minimum thermal conductance occurring near 40% fraction of Si due to a peak in phonon scattering and minimization of thermal conductivity.

Comparison of thermal boundary conductance (TBC) calculated from the virtual crystal diffuse mismatch model (VCDMM) to measured values for several interfaces (Refs. 7 and 8). For each interface examined, the prediction is within 18% of the measured value.
