Measurement Science and Technology &
Scanning Probe Microscopy
The STM is provided with a with an 19” Anfatec-type SPM controller. It includes the 150 V amplification for 6 µm scan range.
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.
