Project title: Thermodynamics of charge defects in ionic crystals.
Supervisors: Prof Mike Finnis, Prof George Jackson, Dr Amparo Galindo and Dr Andrew Haslam
Project description:
The thermodynamics of charged defects are often treated within simulations using the dilute solution model. This holds only at low densities, but in certain systems, such as fuel cells, the concentrations of these defects far exceeds this limit. It is the aim of my work to develop a model which holds for larger concentrations of these defects by employing statistical-mechanical methods such as Monte Carlo techniques and classical density-functional theory. In this way I shall develop a description which bridges the atomic and continuum scales.
