A 300 mK, 9 T, UHV scanning tunneling microscope — •Danny Baumann1, Juliana Brunzlaff1, Torben Hänke1, Christian Hess1, Marko Kaiser2, Ralf Voigtländer2, Dirk Lindackers2, and Bernd Büchner11Institut für Festkörperforschung, IFW Dresden — 2Bereich Forschungstechnik, IFW Dresden

We present the results of first measurements with a 300 mK 9 T ultra high vacuum (UHV) scanning tunneling microscope (STM). This home build STM is equipped with a coarse xy-sample positioning system, in-situ tip exchange as well as a three chamber UHV system to prepare, store and analyze samples.

Furthermore, we show the design of the new home build coarse xy-sample positioning system which is directly mounted on the STM head and works at very low temperatures, high magnetic fields and UHV conditions.
