Abstract
A sample and the tip portion of an alternating current scanning tunneling microscope are electrically enclosed within a cavity with electrically conductive walls. The dimensions of the cavity are smaller than the wavelength of a component of the AC signal applied by the probe to the sample so that the output signal detected by the probe from the sample will not be contaminated by resonant effects of the cavity.
