      A thermoelectric triple-phase p-type Ca3Co4O9-NaxCoO2-Bi2Ca2Co2O9 (CCO–NCO–BCCO) 2D nanocomposite was obtained from pressureless sintering in air. The anisotropic thermoelectric properties of the nanocomposite exhibit a ...
    • Tuning the Thermoelectric Performance of CaMnO3-Based Ceramics by Controlled Exsolution and Microstructuring 

      Kanas, Nikola; Williamson, Benjamin; Steinbach, Frank; Hinterding, Richard; Einarsrud, Mari-Ann; Selbach, Sverre Magnus; Feldhoff, Armin; Wiik, Kjell (Peer reviewed; Journal article, 2022)
      The thermoelectric properties of CaMnO3−δ/CaMn2O4 composites were tuned via microstructuring and compositional adjustment. Single-phase rock-salt-structured CaO–MnO materials with Ca:Mn ratios larger than unity were produced ...
