Dependence of the dielectric tunability in Ba(Zr 0.2 Ti 0.8 )O 3 films deposited on (001) SrTiO 3 substrates on film thickness and temperature" Vol.133, No. 7, This cover image highlights the excellent temperature stability of dielectric properties in Ba (Zr 0.2 Ti 0.8 )O 3 (BZT) films deposited on (100) SrRuO 3 /SrTiO 3 substrates by pulsed laser deposition.The schematic illustrates the capacitor structure used for measurements.The 3D plot showcases the relative dielectric permittivity ( r ) as a function of electric field (E) and temperature, indicating a dielectric maximum (T m ) for the BZT films around 50C.Most notably, the graph on the right contrasts the tunability of these BZT films with bulk BZT, demonstrating that the films maintain a high and stable tunability of approximately 80% over a broad temperature range from -100 to 100C.This remarkable temperature stability underscores the potential of these BZT films for advanced tunable microwave applications.
