Descripción del proyecto
Metal oxide surfaces and interfaces play a key role in energy-related applications and in novel schemes for electronic devices that exploit the special physical and chemical properties of these promising materials.
For progress in both areas, a detailed, mechanistic understanding of the atomic and molecular processes that occur at oxide surfaces and interfaces is critical. Experiments on well-characterized model systems in conjunction with computational modelling can provide such insights, but current investigations are limited in the range of materials and scope of phenomena that can be studied, and to experiments in a low-pressure environment.
Research conducted in this project will push these limits by:
• Developing new methodologies for atomic-scale investigations of the subsurface region of oxides with mixed electronic and ionic conduction to measure mass and charge transport across oxide interfaces.
• Combining cutting-edge molecular beam epitaxy techniques with atomically-resolved scanning tunneling microscopy to synthesize samples of multi-component metal oxide materials with tailored surface properties.
• Establishing a new research thrust that will combine both ex-situ and in-situ electrochemical surface science techniques to study structurally well characterized metal oxide surfaces in an aqueous environment.
