Thermal diffuse scattering (TDS) is a phenomena in which a rich continuous structure is observed in addition to the expected Bragg peaks in X-ray diffraction.  TDS occurs due to the scattering of X-rays by phonons in the crystal.  In my work, I extract information about the lattice dynamics of a crystal by complementing my experimental data with interatomic simulations.

PbTe is high peforming thermoelectric, in part due to its surprisingly low thermal conductivity.  I wish to investigate the lattice dynamics of this material at a range of different temperatures and pressures to determine the origin of this low conductivity
