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…
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…
How local is the Phantom Force?
Thorsten Wutscher, Alfred J. Weymouth, Franz J. Giessibl
The phantom force is an apparently repulsive force, which can dominate the atomic contrast of an AFM image when a tunneling current is present. We described this effect with a simp…
A phantom force induced by the tunneling current, characterized on Si(111)
A. J. Weymouth, T. Wutscher, J. Welker +2
Simultaneous measurements of tunneling currents and atomic forces on surfaces and adsorbates provide new insights into the electronic and structural properties of matter on the ato…
