ABSTRACT:
A scanning tunneling microscope having a scanner driven in three dimensions. A conducting tip is attached to the front end of the scanner. A voltage is applied between the tip and a specimen. Movement of the tip is controlled so that the resulting tunneling current is maintained constant. A scanning tunneling microscope (STM) image is created from a control signal for controlling the movement of the tip. The microscope is equipped with a secondary electron detector for detecting secondary electrons emitted from the specimen when the voltage applied between the tip and the specimen is increased. A secondary electron image originating from the same field of view as the STM image is derived.
