Research Abstract

An electrostatic potential analysis method using convergent-beam electron diffraction has been successfully developed, which enables us to determine electrostatic potential distribution from a nanometer-scale specimen area. Using this method, ferroelectric polarizations of ferroelectric materials such as LiNbO3 were observed through electrostatic potential. The method was also applied to visualization of orbital ordered states of 3d electrons in strongly-correlated electron systems.
