Park Systems Weekly Demo & Chat Sessions is a new series of online, live demonstrations of Park AFM Systems hosted by the Park Systems Technical team. Each week, an engineer from the technical team will lead a short, specific demo and then discuss it with attendees. This is the second session in the new series.
Measuring the electrostatic interaction between the atomic force microscope (AFM) tip and sample is a common technique used to characterize electrically sensitive samples. To characterize the actual potential between tip and sample, kelvin probe force microscopy (KPFM) is used. KPFM is currently standard on Park NX Series microscopes and the baseline technique is supported as the standard for KPFM. Using current NX hardware, however, it is possible to explore other advanced methods of gathering this same KPFM signal, each with their own benefits and tradeoffs. This session will demonstrate how to use advanced KPFM techniques, using current AFM hardware, and explore the advantages of working with these advanced techniques.
