Chemical stability of Ca3Co4−xO9+δ/CaMnO3−δ p–n junction for oxide-based thermoelectric generators
Gunnæs, Anette Eleonora; Tofan, Raluca; Berland, Kristian; Gorantla, Sandeep Madhukar; Storaas, Thomas Aarflot; Desissa, Temesgen Debelo; Schrade, Matthias; Persson, Clas; Einarsrud, Mari-Ann; Wiik, Kjell; Norby, Truls Eivind; Kanas, Nikola (Peer reviewed; Journal article, 2020)An all-oxide thermoelectric generator for high-temperature operation depends on a low electrical resistance of the direct p–n junction. Ca3Co4−xO9+δ and CaMnO3−δ exhibit p-type and n-type electronic conductivity, respectively, ... -
Enhancement of thermoelectric properties by energy filtering: Theoretical potential and experimental reality in nanostructured ZnSb
Berland, Kristian; Song, Xin; Carvalho, Patricia; Persson, Clas; Finstad, Terje; Løvvik, Ole Martin (Journal article; Peer reviewed, 2016)Energy filtering has been suggested by many authors as a means to improve thermoelectric properties. The idea is to filter away low-energy charge carriers in order to increase Seebeck coefficient without compromising ... -

Thermoelectric transport trends in group 4 half-Heusler alloys
Berland, Kristian; Shulumba, Nina; Hellman, Olle; Persson, Clas; Løvvik, Ole Martin (Journal article; Peer reviewed, 2019)The thermoelectric properties of 54 different group 4 half-Heusler (HH) alloys have been studied from first principles. Electronic transport was studied with density functional theory using hybrid functionals facilitated ...
