  • Chemical tracer diffusion of Sr and Co in polycrystalline Ca-deficient CaMnO3-δ with CaMn2O4 precipitates 
    Desissa, Temesgen D.; Kanas, Nikola; Singh, Sathya Prakash; Wiik, Kjell; Einarsrud, Mari-Ann; Norby, Truls Eivind (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) ...
  • Electrical Properties of a p–n Heterojunction of Li-Doped NiO and Al-Doped ZnO for Thermoelectrics 
    Desissa, Temesgen D.; Schrade, Matthias; Norby, Truls Eivind (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2018)
    The electrical properties of a p–n heterojunction of polycrystalline p-type Ni0.98Li0.02O and n-type Zn0.98Al0.02O have been investigated for potential applications in high-temperature oxide-based thermoelectric generators ...
  • Inter-diffusion across a direct p-n heterojunction of Li-doped NiO and Al-doped ZnO 
    Desissa, Temesgen D.; Haugsrud, Reidar; Wiik, Kjell; Norby, Truls Eivind (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2018)
    We herein report inter-diffusion across the interface between p-type Ni0.98Li0.02O and n-type Zn0.98Al0.02O for various applications including p-n-heterojunction diodes and oxide thermoelectrics. Diffusion couples were ...
