The Park systems NX-Hivac has been (a) may be used to perform electrostatic force microscopy (EFM) measurements on parallel stacked hBN, which exhibits a ferroelectric superlattice (b)

The EFM phase images enables the morphology of the ferroelectric domains which are formed mechanically to be mapped spatially with nanometre scale resolution (c).

Dr. James Kerfoot
Application Scientist at Park Systems United Kingdom

James received his PhD in Physics from the University of Nottingham in 2018, studying the morphology and optical properties of monolayers of self-assembled molecules and their heterostructures. He then went on to work as a postdoctoral researcher, also at the University of Nottingham, working on the formation of hybrid heterostructures of molecular assemblies and layered materials demonstrating both electroluminescence and selective triplet excitation. In 2020, James took up a position as a postdoctoral researcher at the Cambridge Graphene Centre, using scanning probe microscopy and optical spectroscopy to study electrostatics and optical properties of layered materials heterostructures with controlled twist angle and their scalable incorporation into integrated photonic circuits. Since January 2022, James has been a member of the Park Systems team as an applications scientist, supporting customers with interest ranging from fundamental physics to industrial scale production in the application of a diverse range of scanning probe microscopy techniques to gain insightful results.
