Nonlinear dielectric imaging with sub-nanometer resolution

2 Nonlinear dielectric imaging with sub- nanometer resolution 

we briefly describe the theory for detecting polarization. Precise descriptions of the principle of the microscope have been reported elsewhere (see [3,4]). We also report the results of the imaging of the ferroelectric domains in single crystals and in thin films using the sndm. Especially in the pzt thin film measurement, we succeeded to obtain a domain image with a sub-nanometer resolution.
