Webinar Overview

Kelvin probe force microscopy (KPFM, also known as surface potential microscopy) measures the work function, or electric potential, of materials or charges on the nanometer length scale. Since its first introduction in 1991, KPFM has found use in a wide range of nano-scale electrical characterization applications on metals, semiconductor materials & devices, organic materials & devices and biological samples. It has proven itself to be a unique and valuable tool.

Despite much effort, KPFM has suffered from its inability to obtain consistent measurements of absolute work-functions in ambient conditions. Contamination, oxidation, and tip-induced electrochemical reactions are all at play and make repeatable quantitative measurements a daunting challenge. Even under ultra-high vacuum, tip-wear can lead to large measurement uncertainty both over time and from probe to probe.

In our new probe and instrument designs, we have found ways to reduce probe to probe measurement scatter to below a standard deviation of 50 mV. This represents a major advance towards quantitative work function measurement, which in turn expands KPFMs utility in ever demanding applications.

The live broadcast will include an interactive Q&A session to answer all of your applications questions. Register today to reserve your seat.

Welcome - about us

Welcome! Nanopaprika was cooked up by Hungarian chemistry PhD student in 2007. The main idea was to create something more personal than the other nano networks already on the Internet. Community is open to everyone from post-doctorial researchers and professors to students everywhere.

There is only one important assumption: you have to be interested in nano!

Nanopaprika is always looking for new partners, if you have any idea, contact me at
