Abstract
A freshly cleaved surface of ferroelectric triglycine sulfate (TGS) ha s been studied by scanning friction force microscopy. Well-defined are as, exhibiting a strong contrast difference, have been found just afte r cleavage in the ferroelectric phase. These regions correspond to dif ferent ferroelectric domains. ''Interactions'' between small regions a nd large negative domains are also observed leading us to conclude tha t these small features could be interpreted as nuclei of negative doma ins inside the positive one, evidence of the domain structure branchin g at the submicron scale.
