| Abstract: |
| Ferroelectric thin films possess ferroelectric,piezoelectric,pyroelectric and photovoltaic properties,which have bright prospect for transducers,actuators,sensors,energy harvesting and solar cells.The properties of ferroelectric films are closely related to their strain due to films constrained by substrates.Therefore,the key to improve the properties of ferroelectric films is how to use substrates to regulate and control their strain,and then regulate their polarized state.This paper review the research progress of regulating the properties of ferroelectric films with perovskite structure by strain engineering and the problems needed to be resolved. |
