It is one of the few and new technological instruments that is able to get measurements to a nanometer scale. It is non-optical but soft-ware controlled.It displays a 3-D image of a conductive and semi-conductice substance topography.

I is is build in a box with foam as to protect the tip from noise. The cable are connected to an outer inlet that connects the STM with the control software || This ia a close up of the piezo tube, the tip and the sample. As you can see this STM scans vertically. The sample is Gold with infused octanethiol. And you see how close is the tip from the sample. || media type="custom" key="484858"
