摘要：

The ferroelectric domain morphology of PbTiO3 single crystals has been investigated at room temperature by electrostatic force microscopy (EFM) and piezoelectric force microscopy (PFM) in addition to atomic force microscopy (AFM). While EFM is shown to reveal 90 degrees a-c-domains via susceptibility contrast and 180 degrees c-domain walls via their stray fields, PFM is used to visualize and to write 180 degrees c-domain patterns. Owing to stabilizing negative space charges provided by the n-type PbTiO3 only negative written c-domains are stable against backswitching.
