Dielectric Ba0.6Sr0.4TiO3 films doped with different weight percentages of TiO2 were deposited by pulsed-laser deposition. The dielectric constant, dielectric loss, and the dielectric tunability of the films were found to be a strong function of the weight ratio of TiO2/Ba0.6Sr0.4TiO3. Compared to the pure Ba0.6Sr0.4TiO3, the TiO2-doped Ba0.6Sr0.4TiO3 exhibits lower dielectric loss while maintaining a significantly adjustable dielectric constant and desirable capacitance tunability. The change of the dielectric properties of TiO2-doped Ba0.6Sr0.4TiO3 films is closely related to the change in microstructure of the films as revealed by transmission electron microscopy. © 2002 American Institute of Physics.
