STABLE LABELING WITH TIME PASSAGE OF INDIVIDUAL ATOM ON SOLID SURFACE, AND STORAGE DEVICE OF INFORMATION UNIT IN ATOMIC SCALE

摘要

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.;COPYRIGHT: (C)1994,JPO
