  4. 3. Theoretical study of Gd2O3-CeO2 (111) interface

    Master-uppsats, KTH/Materialvetenskap

    Författare :Qigui Yang; [2018]
    Nyckelord :Density functional theory; Gd doped ceria; Cluster expansion; Solid oxide fuel cells;

    Sammanfattning : Atomistic modelling has widely been applied for studying structures and properties of materials. There are various methods to perform atomistic modelling. This master thesis presents a combined density functional theory (DFT) and cluster expansion (CE) study of Gd2O3 and Gd2O3-CeO2 interface (GCI) relevant for solid oxide fuel cells (SOFCs). LÄS MER

  7. 5. A first-principles non-equilibrium molecular dynamicsstudy of oxygen diffusion in Sm-doped ceria

    Master-uppsats, Linköpings universitet/Teoretisk Fysik; Linköpings universitet/Tekniska fakulteten

    Författare :Johan Klarbring; [2015]
    Nyckelord :density functional theory; non-equilibrium molecular dynamics; color diffusion; Sm-doped ceria; CeO2; ionic conductivity; solid oxide fuel cells;

    Sammanfattning : Solid oxide fuel cells are considered as one of the main alternatives for future sources of clean energy. To further improve their performance, theoretical methods able to describe the diffusion process in candidate electrolyte materials at finite temperatures are needed. LÄS MER
