Thermal expansion and piezoelectric response of PZT Channel 5800 for use in low-temperature scanning tunneling microscope designs

Abstract

The thermal expansion of the ceramic piezoelectric material PZT Channel 5800 between 2 and 300 K is found to be anisotropic, being negative parallel to the poling direction and positive normal to this direction. The piezoelectric response is temperature dependent, decreasing significantly as the temperature is reduced.
