We have measured the thermal diffusivity and conductivity ofplatinum and MgO periclase at high pressures (P) and hightemperatures (T) by combining the pulsed light heatingthermoreflectance technique with a laser-heated diamond anvilcell.

Thermal diffusivity measurement of silicon samples by a combined piezoelectric and pyroelectric method. [EN]

In the past, when thermal diffusivity measurement of materials were carried out by photoacoustic signal detection using transducers, only the piezoelectric or the pyroelectric property of the transducers was considered. In case the transducer exhibits both piezoelectric and pyroelectric properties.
