Abstract:
In this thesis, phonon transport properties in single crystal and ceramic aluminium nitride (AIN) have been studied. The Callaway theory (within the Debye's isotropic continuum scheme) has been applied in its full form with a detailed account of three-phonon scattering processes in order to calculate the thermal conductivity of different AIN samples. Other phonon scattering processes have also been taken into account. The N-drift contribution, due to the momentum conserving nature of three-phonon Normal processes, to the total conductivity has been quantified. The influence on the thermal conductivity of oxygen-related defects, and grain boundaries in samples studied in this thesis, has been investigated.
