Abstract
A process for the specific, location-selective and time-stable modification of surfaces of solids in the nanometer range without destruction of the atomic order of the surface at the location of the structure or in the vicinity thereof, where a local delamination is caused at the surface of solids having a layered structure due to the action of a local probe. This process is used for the storage of information.
