Interests
Investigation of the physical properties of dielectric, piezoelectric and ferroelectric materials is the main topic of my research interest. In particular, the studies of ferroelectric photovoltaic, photo-ferroelectric and electrostriction phenomena in both centro and non-centrosymmetric systems. My current research focuses on synthesising nanostructured ferroelectric thin films for the development of next-generation solar cell devices, which is an ERC-funded project. We use the AFM technique to characterise the nanostructured thin film.
