Our paper entitled “Low-Field Giant Dielectric Tunability by Polaron-Mediated Interfacial Polarization in Pulsed-Laser-Deposited-Nanocrystalline/Amorphous composite BaTiO3 Thin Films” has been published in Adv. Electron. Mater. BaTiO3 thin films grown under vacuum show giant dielectric tunability at low electric fields due to oxygen-vacancy-induced polaron-mediated interfacial polarization. The films achieve a dielectric constant above 3000 and a record tunability efficiency, enabling high-performance low-voltage tunable dielectric devices.
