Thermal conductivity close to structural phase transitions from first principles
Dr. Hugo Aramberri, The Institut de Ciencia de Materials de Barcelona (ES)

We investigate the thermal properties of BaTiO3 and SiO2 as they undergo pressure-induced structural phase transitions. We calculate their lattice thermal conductivity from first principles in a wide range of temperatures and pressures for both compounds by solving the Boltzmann transport equation self-consistently. SiO2 shows a large anisotropy and a huge enhancement of its thermal conductivity close to the critical pressure. We thus propose SiO2 to work as an anisotropic thermal transistor.
