Sample Preparation for Ferroelectric Switching Measurements

Abstract

Small thin fully electroded disk samples (e.g., 0.05 cm diam by 0.01 cm thick) are necessary for measurements of ferroelectric switching times less than 50 nsec. Techniques are described for forming and processing such disks. Electroded disks are suspended by the lead wires in an oil filled electroded cell for ease and reliability in handling. The cell technique allows high field switching measurements on a large range of sample sizes for determination of dimensional effects.
