Research output: Contribution to journalConference articlepeer-review


The higher order nonlinear dielectric imaging technique using scanning nonlinear dielectric microscopy (SNDM) is investigated. The resolution of the higher order nonlinear dielectric imaging is much higher than that of the conventional nonlinear dielectric imaging which detects the lowest order of the nonlinear dielectric constant. It is also demonstrated that this higher order imaging is very useful for observing a non-ferroelectric surface layer with an unit cell thickness formed on a ferroelectric material.
