| Popis: | The problem of calculation of Kapitza contact thermal resistances between different materials is very urgent in view of the development of various nanosystems (computer electronic circuits, thermoelectric devices, quantum cascade lasers, etc.). An improved acoustic mismatch model is proposed for calculating Kapitza conductivities. A drawback of the current model is the use of the Debye approximation. This leads to limitation of the model’s applicability by the low-temperature region. It is shown that consideration of the wave dispersion ensures good agreement between the theoretical and experimental data in a much wider temperature range in comparison with the application of modern models. |
