AFM tip characterization by Kelvin probe force microscopy
Reliable determination of the surface potential with spatial resolution is key for understanding complex interfaces that range from nanostructured surfaces to molecular systems to biological membranes. In this context, Kelvin probe force microscopy (KPFM) has become the atomic force microscope (AFM) method of choice for mapping the local electrostatic surface potential as it changes laterally d...
متن کاملCharacterization of Potential Inhomogeneities on Passive Surfaces by Scanning Kelvin Probe Force Microscopy
Potential mapping measurements have been performed on passive surfaces in air using an Atomic Force Microscopy based technique, the Scanning Kelvin Probe Force Microscope (SKPFM). A linear relation was found between the potential measured this way and the corrosion potential in aqueous solution for a range of pure metals. The SKPFM can be considered to map the practical nobility of the surface....
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 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 کاملDistinguishing magnetic and electrostatic interactions by a Kelvin probe force microscopy–magnetic force microscopy combination
The most outstanding feature of scanning force microscopy (SFM) is its capability to detect various different short and long range interactions. In particular, magnetic force microscopy (MFM) is used to characterize the domain configuration in ferromagnetic materials such as thin films grown by physical techniques or ferromagnetic nanostructures. It is a usual procedure to separate the topograp...
