Tiptek STM Probes
A Scanning Tunneling Microscope (STM) images a surface with atomic resolution using an electrically biased probe. In this technique, the STM user brings the probe in close proximity to a surface and establishes a tunneling current. While holding current constant, the probe is rastered across the surface and the relief map created from this motion is a direct representation of the atomic structure of the surface. At a given location, the user may also sweep voltage and obtain highly localized information on the electronic structure of the sample in a measurement call scanning tunneling spectroscopy.
