A Next-Generation qPlus-Sensor-Based AFM Setup: Resolving Archaeal S-layer Protein Structures in Air and Liquid
Theresa Seeholzer, Daniela Tarau, Lea Hollendonner +5
Surface-layer (S-layer) proteins form the outermost envelope in many bacteria and most archaea and arrange in 2D quasi-crystalline structures via self-assembly. We investigated S-l…
Unexpected Gaussian line shapes reveal electron-adsorbate interaction as dominant broadening mechanism in quantum corrals
Marco Weiss, Michael Schelchshorn, Fabian Stilp +2
Understanding the factors influencing the lifetime of electronic states in artificial quantum structures is of great significance for advancing quantum technologies. This study foc…
Evidence for temporary and local transition of sp2 graphite-type to sp3 diamond-type bonding induced by the tip of an atomic force microscope
Thomas Hofmann, Xinguo Ren, Alfred J. Weymouth +4
Artificial diamond is created by exposing graphite to pressures on the order of 10\,GPa and temperatures of about 2000\,K. Here, we provide evidence that the pressure exerted by th…
Amplitude dependence of image quality in atomically-resolved bimodal atomic microscopy
Hiroaki Ooe, Dominik Kirpal, Daniel S. Wastl +3
In bimodal FM-AFM, two flexural modes are excited simultaneously. The total vertical oscillation deflection range of the tip is the sum of the peak-to-peak amplitudes of both flexu…
CO Tip Functionalization Inverts Atomic Force Microscopy Contrast via Short-Range Electrostatic Forces
Maximilian Schneiderbauer, Matthias Emmrich, Alfred J. Weymouth +1
We investigated insulating CuN islands grown on Cu(100) by means of combined scanning tunneling microscopy and atomic force microscopy with two vastly different tips: a bare me…
Optimizing atomic resolution of force microscopy in ambient conditions
Daniel S. Wastl, Alfred J. Weymouth, Franz J. Giessibl
Ambient operation poses a challenge to AFM because in contrast to operation in vacuum or liquid environments, the cantilever dynamics change dramatically from oscillating in air to…
