摘要
A technique applying voltage across the tunnel junction for writing permanent features on graphite with lines about 10 nm width using our home-built scanning tunneling microscope has been presented. Multiple-tip effects while modifying the surface are often met. The phenomena are explained in terms of the strong electric field existing at the junctions between the tip and the surface. In addition, the shape of the structure indented by the tip is in agreement with that of the tip.
