Quantitative AC - Kelvin Probe Force Microscopy [PDF]
Microelectronic Engineering, 2017 This paper presents a novel feedback based Scanning Probe Microscopy method which enables quantitative surface potential measurements without the need of the DC bias of Kelvin Probe Force Microscopy. In addition to the sinusoidal excitation signal at frequency , a sinusoidal signal with the frequency 2 is applied to the conductive cantilever.

Note: Switching crosstalk on and off in Kelvin probe force microscopy [PDF]
Review of Scientific Instruments, 2014 In Kelvin Probe Force Microscopy (KPFM) electronic crosstalk can occur between the excitation signal and probe deflection signal. Here, we demonstrate how a small modification to our commercial instrument enables us to literally switch the crosstalk on and off.
