Relaxor characteristics of highly tunable lead-free 0.5Ba(Zr0.2Ti0.8)O3-0.5(Ba0.7Ca0.3)TiO3 thin film grown on LaNiO3/Si by pulsed laser deposition

► Pulsed Laser deposition of lead-free BCZT50 thin film on LNO/Si. ► Dielectric relaxation follows Vogel-Fulcher Relationship. ► Inhomogeneous cationic distribution leads to formation of PNRs. ► Highly tunable BCZT50 thin film with low temperature coefficient. ► Promising material for fabrication of tunable capacitors.
