Study of high–low KPFM on a pn-patterned Si surface

Microscopy (Oxford, England), 2022
Abstract Comparative measurements between frequency modulation Kelvin probe force microscopy (FM-KPFM) using low frequency bias voltage and heterodyne FM-KPFM using high frequency bias voltage were performed on the surface potential measurement. A silicon substrate patterned with p- and n-type impurities was used as a quantitative sample.

Towards nanoscale electrical measurements in liquid by advanced KPFM techniques: a review

Reports on Progress in Physics, 2018
Fundamental mechanisms of energy storage, corrosion, sensing, and multiple biological functionalities are directly coupled to electrical processes and ionic dynamics at solid-liquid interfaces. In many cases, these processes are spatially inhomogeneous taking place at grain boundaries, step edges, point defects, ion channels, etc and possess complex ...

Contact electrification and charge decay on polyester fibres: A KPFM study

Journal of Electrostatics, 2018
Abstract Surface contact electrification experiments have been performed on insulating polyester fibres in contact with a conductive fibre using biased atomic force microscopy tips. With positive tip bias, charge spots have been deposited in a reproducible manner.

Quantitative 3D-KPFM imaging with simultaneous electrostatic force and force gradient detection

Nanotechnology, 2015
Kelvin probe force microscopy (KPFM) is a powerful characterization technique for imaging local electrochemical and electrostatic potential distributions and has been applied across a broad range of materials and devices. Proper interpretation of the local KPFM data can be complicated, however, by convolution of the true surface potential under the tip

Time resolved surface photovoltage measurements using a big data capture approach to KPFM

Nanotechnology, 2018
Optoelectronic behavior in materials such as organic/inorganic hybrid perovskites depend on a complex interplay between fast (electronic) and slower (ionic) processes. These processes are thought to be influenced by structural inhomogeneities (e.g. interfaces and grain boundaries) bringing forward the necessity for development of techniques capable of ...
