Scanning Tunneling Microscopy, STM
The new STM Module made by S.I.S. extends the universal AFM-controller SCANControl C by the ability to measure the topography by tunneling current. Finally the well-known STM technique is also available in the usual small ULTRAObjective format. The scanning head is 45 mm long and has 34 mm diameter. Like all ULTRAObjectives it may be integrated into the turret of an optical microscope, but for highest resolution we recommend the PICOStation.

Highest resolution with STM

Atomic resolution on highly oriented pyrolythic graphite (HOPG).  The unprocessed data demonstrates the excellent system performance.
Image size is 2.5 nm by 2.5 nm.
