Notes:
The scanning tunneling microscope (STM) can produce high-resolution topographic images of surfaces which, normally, are electrically conducting. We have made STM images of a variety of insulating surfaces which are made conducting by a smooth ultrathin (〉20 A(ring) thickness) Au overlay film. Topographic features of the underlying substrate as small as 10 A(ring) are resolved. Surprisingly, no features of the overlay Au film are seen. These films are useful for obtaining topographic images of a wide variety of surfaces and for STM measurements where a stable conducting surface is required for support of molecules or other microscopic structures.
