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.
- Constant Height: the tip probes the surface in a straight line and at the same time the tunneling current is recorded
- 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
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.
