Abstract
A Photon Scanning Tunneling Microscope is presented in which Si3N4 cantilevers are used as optical probes. This method allows close contact scanning without tip destruction. Simultaneous measurement of the optical signal and the deflection of the cantilever permits a comparison between the optical image and the topography. The optical signal as a function of the distance clearly shows the exponential behaviour of the evanescent field. Several structures have been examined, giving a lateral resolution in the optical image of about 40 nm.
