Development of a high-resolution SFM for use in a UHV cryogenic temperature environment — •Lutz Tröger und Michael Reichling — Universität Osnabrück, Barbarastr. 7, 49076 Osnabrück
We describe the development of a high-resolution SFM for use in a UHV cryogenic temperature environment. The design concept aims at highest resolution studies and is optimised for atomic precision force spectroscopy. The microscope utilises a laser interferometer for cantilever oscillation detection and an integrated eddy current damping stage to reduce mechanical noise. Additionally the commercial LHe/LN2-bath-cryostat providing the cooling is equipped with a second stage of external kinematic vibration damping. We demonstrate the capability of the detection and scanning system and show first test measurements concerning mechanical stability and functionality.
