Surface potential measurement, KTP crystal

A poled KTP crystal was re-measured with the ICON AFM, using PeakForce KPFM mode. Here settings and result are shown.

Topography
Please note that the weakly visible squares at the lower right do not seem to be poled anymore, no signal in the potential image. The sample is several years old.
