Piezoelectric materials deform shape in response to an electric field and are used in everything from high-tech atomic force microscopes (AFM) to airbag impact sensors in cars. Our group is creating nanoscale piezoelectric materials with high deformation. Potential applications include energy generation and highly sensitive sensors.
We use computational modeling to understand the connection between molecular structure and piezoelectric response. Based on these simulations, we have started developing “design rules” for synthetic organic piezoelectrics and are using a variety of experimental techniques to characterize monolayers and thin films to characterize this phenomenon.
