Scanning Tunneling Microscopy (STM) measures topography of surface electronic states using a tunneling current that is dependent on the separation between the probe tip and a sample surface.

STM is typically performed on conductive and semiconductive surfaces. Common applications consist of atomic resolution imaging, electrochemical STM, Scanning Tunneling Spectroscopy (STS) union and low current imaging of less conductive samples.
