摘要
The sol-gel technique has been used to produce perovskite PZT thin films on lattice-matched SBN:60 and LaAlO3 substrates. These films were spin-coated and then annealed in the range of 500 - 700 degrees C in an oxygen atmosphere. Highly grain oriented films showed high polarization and the potential for a large electro-optic response. In all cases, the PZT thin films were highly crystalline, with dielectric constants > 1300. PZT films were also deposited on Pt-metallized Si using the same deposition technique in order to establish the effect of annealing conditions on the formation of pyrochlore phase.
