Chemical labeling of the surfaces of solids on an atomic scale, and the storage of information units in the atomic range

摘要

A process useful for the reversible storage of information units involves the targeted, positionally selective and time-stable labeling of individual atomic positions or groups of such positions on the surface of a solid by chemical reaction with foreign atoms or molecules or by chemisorption, with the lateral atomic order of the surface in each case being retained, even on a local level.
