    摘要： A cantilever type probe comprises a cantilever-shaped displacement element and a tip which displacement element has a first electrode layer, a first piezoelectric material film and a second piezoelectric material film which films are laminated on opposite sides of the first electrode layer, and a second electrode layer and a third electrode layer which layer are laminated on outer surfaces of the piezoelectric material films, and which tip is connected with a leader electrode located at a free end of the surface of the displacement element; wherein in the width direction of the cantilever both ends of the first electrode layer protrude outward more than each end of the second and third electrode layers. A scanning tunneling microscope comprises the cantilever type probe, a driving means for displacing the probe, a stage for specimen so as to approach and locate the specimen to the tip, and a potential applying means for applying a bias voltage between the tip and the specimen. An information processing apparatus further comprises a second potential applying means for applying a pulse and bias voltage between the tip and the recording medium; wherein an information is written on the recording medium and an information in the recording medium is read out by electric current flowing between the tip and the recording medium.

    摘要： A method and structure in which an adsorbate atom or molecule is repositioned on a substrate surface by moving the tip of an STM to a position adjacent to the atom to be moved and causing the atom to be attracted to the tip. While the atom remains bound to the surface (or, alternatively, is lifted), the tip is moved laterally to drag (or carry) the atom to a desired position at which it is bound to the surface.The atom may be repositioned in close proximity to an atom of the same or another type on the same or a different substrate to create a desired multi-atom structure or synthesize a molecule, or an atom may be removed to cleave a multi-atom structure, or a change in state of a multi-atom structure may be effected.Atoms may also be repositioned to write indicia on a storage medium by dragging or carrying atoms into the desired information-bearing pattern, for example, by dragging or carrying selected atoms out of a respective one of a plurality of parallel atom rows using the tip of an STM to thereby write indicia at locations denoted by the removed atoms.
