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 $a T ∕ v_{Debye} < 0.01 \times 10^{- 9} K s$ , 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.
