Complexity of defects

The structure and stability of ceria films grown on mismatched substrates have been studied computationally. A 36% lattice mismatch in growth of CeO on YSZ is found to be accommodated by the formation of islands and dislocation arrays such as edge and screw dislocations. A configuration obtained by simulation is shown in Fig. 9.2 and demonstrates the complexity of defect structures that might...
