Title: Observation method of very small domain in ferroelectric body
Inventor: OKAMOTO MASAKUNI
IPC: G01N37/00
Filed: 1995-05-11
Abstract: PURPOSE: To obtain an observation method in which the domain shape in the very small ferroelectric body of a specific size class and the sign and the magnitude of a polarization can be observed by a method wherein fullerene-based semiconductor ultrafine particles are used, they are ionized inside a gas, a positive ion group and a negative ion group are obtained and ions of one sign out of them are adsorbed selectively by accelerating an electric field. CONSTITUTION: A powder by fullerene C60 fine particles 11 is injected into a region 16 between a counter electrode 13 and a counter electrode 14 in a nitrogen atmosphere. The fine particles 11 are ionized so as to be electrified to a positive electric charge. A DC voltage 12 at 1V is applied across the electrodes in such a way that the upper electrode 13 becomes negative as compared with the lower electrode 14. As a result, the fine powder which is charged to be negative out of the fine powder which has been convection-diffused is accelerated to an electric field so as to be moved downward, and the powder which has been electrified to be positive is moved upward. Fine particles 17 which are electrified to be negative are passed through a hole in the electrode 14, and they are adsorbed selectively to the positive region of a polarization on the surface of a ferroelectric-body sample 18. An adsorption phenomenon is continued until the negative electric charge completely offsets a surface polarization, and it reaches a height of 10nm. Surface uneven parts formed by the adsorbed fine particles are observed with a scanning atomic force microscope or the like, and the shape of a very small domain 19 in a size of 50nm can be known.
