Open loop Kelvin probe force microscopy with single and multi-frequency excitation.
Conventional Kelvin probe force microscopy (KPFM) relies on closed loop (CL) bias feedback for the determination of surface potential (SP). However, SP measured by CL-KPFM has been shown to be strongly influenced by the choice of measurement parameters due to non-electrostatic contributions to the input signal of the bias feedback loop. This often leads to systematic errors of several hundred m...
متن کاملKelvin probe force microscopy in liquid using electrochemical force microscopy
Conventional closed loop-Kelvin probe force microscopy (KPFM) has emerged as a powerful technique for probing electric and transport phenomena at the solid-gas interface. The extension of KPFM capabilities to probe electrostatic and electrochemical phenomena at the solid-liquid interface is of interest for a broad range of applications from energy storage to biological systems. However, the ope...
متن کاملPractical aspects of Kelvin probe force microscopy
We discuss practical aspects of Kelvin probe force microscopy ~KFM! which are important to obtain stable images of the electric surface potential distribution at high spatial resolution ~,100 nm! and high potential sensitivity ~,1 mV! on conducting and nonconducting samples. We compare metal-coated and semiconducting tips with respect to their suitability for KFM. Components of the metal coatin...
متن کاملHigh spatial resolution Kelvin probe force microscopy with coaxial probes.
Kelvin probe force microscopy (KPFM) is a widely used technique to measure the local contact potential difference (CPD) between an AFM probe and the sample surface via the electrostatic force. The spatial resolution of KPFM is intrinsically limited by the long range of the electrostatic interaction, which includes contributions from the macroscopic cantilever and the conical tip. Here, we prese...
متن کاملResolution and contrast in Kelvin probe force microscopy
The combination of atomic force microscopy and Kelvin probe technology is a powerful tool to obtain high-resolution maps of the surface potential distribution on conducting and nonconducting samples. However, resolution and contrast transfer of this method have not been fully understood, so far. To obtain a better quantitative understanding, we introduce a model which correlates the measured po...
