摘要
We have investigated domain structure and dynamics of a triglycine sulfate (TGS) single crystal with a dynamic contact mode electrostatic force microscope (DC-EFM), which is operated in contact mode. DC-EFM can overcome a problem in conventional noncontact EFM measurement, The temperature dependence of surface charge density was measured by a nulling technique, We also investigated local domain switching behaviors of TGS single crystal and PZT thin film. Complex pattern was written on a PZT thin film by the polarization reversal. A writing capability such as a writing speed and voltage dependence in PZT film has been studied by DC-EFM.
