| Abstract |
This paper describes a new type of acoustic microscope based upon a scanning tunneling microscope (STM). This is an STM with an acoustic sensor that obtains physical information from an acoustic wave as well as the tunneling current. Interactions capable of generating strains in the STM sample are detectable and are used to image sample properties. This enhances STM's capabilities without reducing its ability, and enables imaging of nonconducting materials and imaging of dielectric and piezoelectric properties.
