Design and first results of a ultra low temperature scanning tunnelling microscope — •Danny Baumann1, Martha Scheffler1, Ronny Schlegel1, Torben Haenke1, Christian Hess1, Marko Kaiser2, Ralph Voigtländer2, Dirk Lindackers2, and Bernd Büchner1 — 1Institut für Festkörperforschung, IFW Dresden — 2Bereich Forschungstechnik, IFW Dresden
We present the design of a home build 300 mK, ultra high vacuum (UHV) scanning tunneling microscope (STM). The STM is equipped with a 9 T superconducting magnet, a home build xy-sample positioning system, in situ tip and sample exchange, radio frequency filter for all relevant signals as well as a three chamber UHV system to prepare, analyze and store tips and samples.
Furthermore, we show the results of energy calibration measurements with different tip-sample configurations using a Niobium BCS superconductor.
