- Abstract
In this work, (111)-oriented (PbNb)(Zr, Sn, Ti)O (PNZST) antiferroelectric thin films, which located in the tetragonal phase region (PNZST) and the orthorhombic phase region (PNZST), respectively, were successfully fabricated on platinum-buffered silicon substrates by radio-frequency magnetron sputtering technique. The microstructure, dielectric properties, electric field induced phase transition, associated with the energy-storage performance and pyroelectric energy harvesting behavior (by Olsen cycle) were studied systemically. The PNZST thin film showed a diffused field-induced antiferroelectric-ferroelectric (AFE-FE) phase switching with a slim double hysteresis loop, while the PNZST film demonstrated an AFE-FE phase switching with a square double hysteresis loop. A maximum recoverable energy-storage density of 16.4 and 12.4 J/cm were obtained in the PNZST and PNZST film, respectively. Moreover, a huge harvested energy density per cycle of W = 7.35 and 5.35 J/cm was also predicted in the PNZST and PNZST film at 1 kHz, respectively. The good energy-storage performance and giant thermal-electrical energy harvesting effect of the PNZST antiferroelectric thin films maybe make a great impact on the modern energy-storage technology and the thermal-electrical energy harvesting applications.
