Oxygen migration energy in La and Y Co-doped CeO2: Effect of lattice constant and grain boundary segregation
The transfer energy of oxygen vacancy of La and Y co-doped CeO2 is investigated in which the total amount of La and Y is fixed at 20 at%. Although both the La3+ (1.16 Å) and Y3+ (1.032 Å) ions are larger than the Ce4+ ions (0.97 Å), individual single doping of La and Y results in an increase and a d...
