ABSTRACT:
The invention concerns a reading/writing tip configured in the shape of a needle consisting of a core of refractory material covered with a coating of electrically conductive material, and having an outer microscope needle geometry by tunnel effect, to obtain an information concerning a surface through tunnel-effect microscopy The needle emits a charged particle from the layer of electrically conductive material, to form the surface. The tip comprises a reservoir capable of being liquefied to flow along the tip.
