DIRECT OBSERVATION OF FERRO-ELECTRIC DOMAINS IN TRIGLYCINE SULPHATE (T. G. S.) USING THE SCANNING ELECTRON MICROSCOPE (S. E. M.)

The conditions necessary for a good observation of insulating samples (without metallization) with a S. E. M. are calculated. The application to the study of ferroelectric T. G. S. crystals is made : observation of antiparallel domains without modification of its surface, modification and nucleation of domains by the electron beam
