Chemical tracer diffusion of Sr and Co in polycrystalline Ca-deficient CaMnO3-δ with CaMn2O4 precipitates
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2018)
Diffusivity on the A- and B-site of polycrystalline perovskite CaMnO3-δ with Ca deficiency and spinel CaMn2O4 (marokite) as a secondary phase was studied using chemical tracers and secondary ion mass spectrometry (SIMS) ...
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)
High-temperature instability of the Ca3Co4−yO9+δ and CaMnO3−δ direct p-n junction causing the formation of Ca3Co2−xMnxO6 has motivated the investigation of the thermoelectric performance of this intermediate phase. Here, ...
Thermoelectric properties of A-site deficient La-doped SrTiO3 at 100–900 °C under reducing conditions
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2020)
Lanthanum doped strontium titanate is a potential n-type thermoelectric material at moderate and high temperatures. (La0.12Sr0.88)0.95TiO3 ceramics were prepared by two different routes, conventional sintering at 1500 °C ...
