High Pressure Structural and Electrical Transport Properties of the Ca$_{3}$Co$_{4}$O$_{9 }$System
POSTER
Abstract
High pressure and temperature dependent resistivity measurements were conducted on the Ca$_{3}$Co$_{4}$O$_{9}$ system to understand the influence of internal pressure by doping on the properties of these materials. To directly probe the effect of pressure on the structure, x-ray diffraction measurements under pressure were also conduct with diamond anvil cells at ambient temperature. The results are compared with ambient pressure chemically materials. The influence of the atomic structure on the thermoelectric properties will be discussed.
