Abstract: PURPOSE: To change selectively and eliminate reversibly a pattern with a nm range of a solid surface by positioning a pattern with an space of Å range on a solid surface, or moving a tip of a surface sensitive scanning probe contacted to the surface on a surface pattern at practically same height level. CONSTITUTION: A tip of an extra fine surface sensitive scanning probe, that is a scanning tunneling microscope(STM) or the like, is positioned right above a pattern with a nm range which is desired to be changed. Next, by moving it with a certain space kept from x/y surface of a specimen surface of a pattern which is not changed yet, a change of the pattern is mechanically formed by a very fine probe, or formed by applying a voltage pulse between the specimen and the probe. Thereby, it becomes possible to form a pattern to maintain an atomic arrangement of the solid surface observed by STM on the pattern itself and around it. As a result, an image is formed with atomic resolution, and writing, reading, treatment of changes and erasing can be done freely at any place.

Abstract: PURPOSE: To provide a method for recording stable information at a density higher than heretofore particularly without bringing the partial destruction of atom lattice by imparting stable flags to the atoms or atom groups on a solid surface. CONSTITUTION: The method for imparting the flags stable with lapse of time to the individual atoms or atom groups on the solid surface includes a stage of converting the individual atoms or atom groups to the structural or electronic state different from the initial state without drastically changing the atom lattice structure parallel with the solid surface and without bringing the participation of the different atoms.

Abstract: PURPOSE: To stabilize the accumulation of information with lapse of time by enabling the selective removal of atoms from a solid surface without changing the lattice structure of the remaining atoms at the time of labeling the discrete atoms or atom groups including compds. or completely intimately mixed allays on the solid surface. CONSTITUTION: A high information density is obtd. by storing the information on the atom regions at the time of storing or writing information units. Namely, erasure is made possible again by recombining vacancy to the atoms or atom groups, by which the restoration of the original state is made possible. The recombination is effected on the surface of the solid and more particularly the semiconductor layer of doped chalcogenide, etc., to this size, for example, by using the needle-like electrode of a sensitive surface scanning probe of a scanning tunnel microscope or scanning atomic microscope and applying a short time of an electric field or magnetic field to the surface. The max. limit electric field surface of the semiconductor layer surface of this kind of the probe is 10 to 0.1nm and, therefore, a linear influence is exerted on the electron structure and the desorption of the specific one kind of the atoms is made possible.

Abstract: PURPOSE: To attain information storage being stable with time passage by re-arranging an individual doping atom or a doping atomic group at a position which is previously fixed by means of a surface scale. CONSTITUTION: The surface of a bi-diselenide sample is made into an image by an atomic dissociation using a scanning tunneling microscope at first. It is superimposed on a tunnel voltage between a tunnel tip on the sample and the sample. In succeeding sample scanning, surface structure with expansion in the horizontal direction, which is increased by the standard of the voltage pulse, is given. The group adding the three atoms is specially degraded here and a relative position correctly corresponds to the position of the tunnel tip at the time of a pulse. By the method, a pattern can be written in the sample and the atom is labeled at the position where the respective voltage pulses are decided so that stereoscopic or electronic configuration is degraded by it.

Abstract: PURPOSE: To carry out labeling stably with lapse of time by targeting a solid surface at an atom scale. CONSTITUTION: This method is effective for reversibly storing information units including the labeling stable with lapse of time by targeting the individual atom positions of the solid surface or the groups of these positions by the chemical adsorption by the chemical reaction with external atoms or molecules or the atom arrangement in the transverse direction of the surface held even at partial levels in the respective cases and selecting the positions.
