Scanning Tunneling Microscope (STM)

About the easyScan STM:

STM (Scanning Tunneling Microscopy) is a scanning probe microscope that utilizes a circuit that adjusts the height of the tip according to current variations that are dependent upon surface deviations. STM identifies a change in voltage as a result of the tip distance from the surface. This difference equates to an image that displays surface variations.

Operation Modes:
  1. Constant Height: the tip probes the surface in a straight line and at the same time the tunneling current is recorded
  2. Constant Current: the tip probes the surface so that the tunneling current is kept constant by the controller. The change in tip height is recorded
Software:

Image Metrology's Scanning Probe Image Processor contains many analytical and visualization tools, including Fourier Imaging, force curve analysis, roughness analysis, tip characterization, and 3D visualization.
