Observation of short-lived local polar states induced by applied tip biases in BaTiO3-based relaxor ferroelectric ceramics

Li, Qian; Liu, Yun; Cheng, Zhao; Bian, Jianjiang; Chen, Hua; Withers, Ray L.

Description

Using piezoresponse force microscopy imaging and spectroscopy methods, surface polar states induced by applied tip biases in the ergodic/paraelectric phase of a BaTiO3-based relaxor ferroelectric ceramic have been observed. The induced polar state appears to be short-lived (typical lifetime only a few seconds) and dependent on the voltages applied and their duration. The observed piezoresponse hysteresis and relaxation behavior is primarily interpreted with respect to the picture of the polar...[Show more]
