Improving our home-built, low-noise, combined STM/AFM operating at 5.7K — •M. Weiss, F. Huber, J. Berwanger, F. Stilp, and F.J. Giessibl — University of Regensburg, 93040 Regensburg, Germany

The combination of a scanning tunneling and an atomic force microscope (STM and AFM) allows investigating several physical phenomena at the same time. Here we discuss potential improvement capabilities of our home-built combined STM/AFM operating at liquid helium temperatures which recently was used to directly probe the transition from physi- to chemisorption [1]. The potential upgrade involves increasing the microscope's mechanical stiffness, improve its thermal anchoring and changing the inertia coarse approach to a sequentially operating Pan Walker.
