Mechanics & Accessories

The STM is provided with a with an 19” Anfatec-type SPM controller. It includes the 150 V amplification for 6 µm scan range.

STM tungsten tip etching Tool


The tip etching tool is provided with a detailed description and a students practical training advice.

It is based on the droplet technique, which was first published in 1999. In combination with a power supply with current limitation one can reach STM tip diameters below 10 nm with over 50 % reproducibility.
