Abstract

Thin films of lead-titanate were deposited by chemical vapor deposition (CVD) using tetraethyl lead and titanium isopropoxide. Good high frequency hysteresis curves were obtained with platinum contacts. Low resistance of the material (estimated at 108 ohm-cm) affected low frequency measurements.

Optimized experimental parameters (pressure, temperature, gas flows, oxidizer) were derived from a designed experimental matrix using response surface methodology. This approach significantly reduced the number of deposition trials required.
