Titel
Nondestructive evaluation of elastic and piezoelectric properties of ferroelectrics using atomic force acoustic microscope and ultrasonic piezomode techniques
Abstract
Atomic Force Acoustic Microscope and ultrasonic piezo-mode have been applied in order to investigate the influence of the local polarization on the elastic and the piezoelectric properties of ferroelectrics. The lateral resolution of both imaging techniques is below 10nm and hence sufficient to image the elastic and piezoelectric properties of nanocrystalline lead calcium titanate thin-films as well as coarse-grained ceramics of barium titanate and lead zirconate titanate.
