Scanning probe microscopy with the Koala drive
We have developed a new type of ultra-compact piezoelectric motor, the so-called Koala drive, which has a diameter of less than 2.5 mm. The Koala drive operates in ambient conditions as well as in ultra-high vacuum, at low temperatures (4 K) and in magnetic fields. The Koala drive serves as the heart of a new STM design: Due to its compactness, a 4-tip STM or nanoprober with an outer diameter of only 50 mm can be built.
