摘要: High-vacuum scanning force microscopy of the domain structures in PMN-PT single crystals is investigated. It has been shown that under high vacuum conditions, polarization charges are not effectively compensated for by intrinsic screening from ferroelectrics. This result suggests electrostatic tip–sample interaction plays a great contribution to imaging mechanism ferroelectric conditions.
