Phonon Scattering in Lightly-Neutron-Irradiated Diamond
The role of defects in limiting the thermal conductivity of synthetic diamond films has not been fully explored. In order to shed light on phonon-defect interactions in this material, we have studied the thermal conductivity of single crystal diamond irradiated with fast neutrons. For low fluences neutrons produce lattice vacancies and small regions of disordered carbon , two important types of defects which occur in diamond films.
