2023 Webinar | Asia
Electrostatic and Kelvin probe force microscopies (EFM and KPFM) have become primary tools for the characterization of electrical phenomena on the nanometer scale, with multiple applications for ferroelectrics, photovoltaics and energy devices.
In this workshop, we shall explore the characteristics of different modes like EFM, AM-KPFM and Sideband KPFM.
Ferroelectricity is observed in hexagonal boron nitride(hBN) through control of the registry of stacked layers, which we explore through both amplitude-modulated and sideband Kelvin probe force microscopy (KPFM) on the Park FX40 automatic AFM.
A schematic of the formation of parallel stacked bilayer hBN is shown in addition to a contact potential difference map measured using sideband KPFM.
