摘要： PURPOSE: To obtain a high-density information storage device by using the level and position of an application electric field required for generating the tunneling current of a charge transfer complex as an information recording medium. CONSTITUTION: The tip of a probe 2 of a scanning tunneling microscope is arranged extremely close to a charge transfer complex film 1. A piezoelectric three-axis actuator 3 is controlled so that the tip of the probe 2 is moved in X, Y, and Z directions by a computer 5. A tunnel voltage is supplied to the surface of the film 1 by a bias power supply 8, an electric field is generated at the film 1 while the tip of the probe 2 is moved, and an electron density on the surface of the film 1 is changed and recorded as data. Then, a distance Z between the tip of the probe 2 and the film 1 is changed, the distance Z where a tunneling current is generated is measured and is taken out as a digital computer image in combination with the distances X and Y in horizontal direction, thus obtaining a high-contrast image with a nm-level resolution.

摘要： PURPOSE: To attain information storage of very high density for a storage medium by impressing an electric field, with a probe tip of a scanning tunneling microscope, to the data storage medium consisting of the charge transfer complex film of an organic metallic charge transfer comple material, and thereby causing change of electron density on the surface of the medium. CONSTITUTION: The tip end of the probe 2 of a scanning tunnelling microscope very close to an organic metallic charge transfer complex film 1. This tunnel voltage is supplied to the film surface by a bias voltage power supply 8 and, if a gap between the probe tip end and the film surface is so small as to generate a tunnel effect, a tunnel current is indluced. Then, piezo-electric tri-axial actuator 3 forms a registration system for a device that controls in the x, y, z direction the movement of the probe tip end moving along the surface of the charge transfer complex film. These movements are controlled by a computer 5. As a result, the change in the electron density of this complex film 1 is used for storing binary data highly densely.
