Research topic: Electronic and Thermal Transport in CaO(CaMnO₃)_m-based Materials for Energy Conversion Applications

My research focuses on CaO(CaMnO₃)_m-based materials; these are n-type thermoelectric oxides promising for waste heat recovery at elevated temperatures. Their electronic and thermal transport is dominated by the density of CaO/CaMnO₃ interfaces (m) acting as scattering centers for charge and heat carriers. We employ point defect engineering and phase mixture to optimize the materials’ electronic and thermal transport properties for energy conversion applications, elucidating the underlying physics linking atomistic structure and charge and heat transport in oxides.
