Abstract
We used a scanning force microscope (SFM) to study the domain structur es of ferroelectric GASH crystals. The SFM was operated in the static contact as well as dynamic non-contact mode. In the static contact mod e the ferroelectric plus and minus domains show opposite contrast. Ope rating the SFM in the dynamic non-contact mode the domain walls are re vealed. The latter technique was improved and its advantage in compari son with scanning electron microscopy is discussed.
