A duality between surface charge and work function in scanning Kelvin probe microscopy
Isaac C. D. Lenton, Felix Pertl, Lubuna Shafeek +1
Scanning Kelvin probe microscopy (SKPM) is a powerful technique for macroscopic imaging of the electrostatic potential above a surface. Though most often used to image work-functio…

No time for surface charge: how bulk conductivity hides charge patterns from KPFM in contact-electrified surfaces
Felix Pertl, Isaac C. D. Lenton, Tobias Cramer +1
Kelvin probe force microscopy (KPFM) is a powerful tool for studying contact electrification, using an tiny tip to image voltages caused by transferred charge. It has been used in…
