School of Physics...),and transmission electron microscopy(TEM).The effective piezoelectric property of individual NBT nanofiber was examined by piezoresponse force microscopy(PFM).The NBT nanofibers crystallized in pure......
cause serious displacement errors (10%-15%), which disallow precise position control of a sample. Its source is known to be primarily from piezoelectric hysteresis of a piezoelectric ceramic actuator. Most piezoelectric actuators have piezoelectric, ferroelectric and ceramic properties simultaneously
