Phthalocyanine Film on HOPG

Topography image shown in 3D of crystalline domains in a non-planar phthalocyanine film grown on a highly ordered pyrolitic graphite substrate. Phthalocyanine is of interest for potential applications as an organic semiconductor. Imaged on a MFP-3D AFM. Scan size 25 µm. Image courtesy of Luke Rochford, University of Warwick.
