WebNov 17, 2024 · We find an ultralow thermal conductivity (κ) of 0.33 W m −1 K −1 at room temperature, in excellent agreement with the experimental measurement. Such ultralow κ is attributed to the strong phonon–phonon scattering that arises from the dense and intertwined low-frequency phonons. WebJan 1, 1987 · Abstract The thermal conductivity, λ, of high purity single crystals of AIN has been measured from 0.4 to 1800 K. These results show that the heat conduction is by phonons and that at the lowest temperatures the phonon mean-free-path, l, is limited by boundary scattering.
