Abstract

A simple, inexpensive circuit to generate a two-dimensional raster pattern for use in a scanning tunneling microscope is presented. The circuit is constructed from common analog and digital integrated circuits. Externally provided dc voltages and the use of analog multipliers allow for easily programmed scan ranges and the system is easily expanded for higher density images. Interfacing to personal computer-based data acquisition and video frame grabber boards is discussed.
