Annotatsiya
The heat fluxes in dielectric point contacts in the pure (ballistic) limit. An anomaly is detected in the temperature dependence of the thermal conductivity. A method is formulated for the determination of the characteristics of the constant-energy surfaces for phonons on the basis of experimental data.
