Design of a dip stick 4 K scanning tunneling microscope — •Ronny Schlegel1, Torben Hänke1, Danny Baumann1, Christian Hess1, Marko Kaiser2, Ralf Voigtländer2, Dirk Lindackers2, and Bernd Büchner1 — 1Institut für Festkörperorperforschung, IFW Dresden — 2Bereich Forschungstechnik, IFW Dresden
To study electronic and surface structures with scanning tunneling spectroscopy (STS) we designed a STM for temperatures from 300 K down to 4 K. The microscope will be placed in a 4He cryogenic system with a superconducting coil (up to 17 Tesla) or in a standard lab Dewar for zero field measurements. An implemented cleaving mechanism allows sample preparation at low temperatures.
