[14p-414-3] An experimental study on polarization charge density measurement of GaN by noncontact scanning nonlinear dielectric potentiometry

〇Kohei Yamasue¹, Yasuo Cho¹ (1.Tohoku Univ.)

Keywords:scanning nonlinear dielectric microscopy, scanning nonlinear dielectric potentiometry, spontaneous polarization

Scanning nonlinear dielectric potentiometry can be used for the measurement of polarization charge density. In this report, we discuss the measurment of spontaneous polarization on GaN.
