Calibrating torsional eigenmodes of micro cantilevers for dynamic measurement of frictional forces
Per-Anders Thorén, Riccardo Borgani, Daniel Forchheimer +1
Non-invasive thermal noise calibration of both torsional and flexural eigenmodes is performed on numerous cantilevers of 10 different types. We show that for all tipless and short-…

A virtual instrument to standardise the calibration of atomic force microscope cantilevers
John E. Sader, Riccardo Borgani, Christopher T. Gibson +12
Atomic force microscope (AFM) users often calibrate the spring constants of cantilevers using functionality built into individual instruments. This is performed without reference t…

Imaging high-speed friction at the nanometer scale
Per-Anders Thorén, Astrid S. de Wijn, Riccardo Borgani +2
Friction is a complicated phenomenon involving nonlinear dynamics at different length and time scales[1, 2]. The microscopic origin of friction is poorly understood, due in part to…
