Citation Info:The low temperature lattice thermal conductivity of twinned and untwinned, martensitic and non-martensitic, Indium-Thallium alloys has been measured to probe the effect of twin boundaries on phonon thermal transport. The phonon scattering by electrons, sample surfaces, dislocations, and impurities is accounted for adequately by existing theoretical models. The reduced lattice thermal conductivity seen in the twinned samples is attributed to additional phonon scattering by twin boundaries and, for the polycrystalline samples, by grain boundaries. Phonon scattering by twin boundaries is well represented by the acoustic mismatch model.
