Current Research: Research focuses on mapping and understanding the manner in which reduced size and increased morphological complexity affect the switching behaviour of meso and nanoscale ferroelectrics. Our approach is to make devices incorporating single crystal ferroelectric material which has been machined to thin film dimensions using Focused Ion Beam milling. Piezoresponse Force Microscopy is used to visualise explicitly the dynamics of domain wall motion during switching.
