Thermal transport across nanosized constrictions is calculated considering wave effects. It is shown that Rayleigh-type phonon diffraction reduces thermal transport across nanosized constrictions at low temperatures. We show that for a T / v Debye < 0.01 × 10 - 9 K s , where a is the radius of the constriction, T the temperature, and v Debye the Debye velocity of the solid material, diffraction effects are important.
