In the past there has been limited success with special geometry and non-bulk nanomaterials. In this work several APT sample preparation techniques were trialed on zirconia NPs. The main characterizations were performed using scanning electron microscopy (SEM) and Focused Ion Beam (FIB). Electrophoresis and dispersions were trialed for parameter optimizations. The decrease in electrophoretic deposition time and voltage decreased the density of NPs and agglomerates deposited on to pre-sharpened APT tips.born digitalmasters thesesengCopyright of the original work is retained by the author.electrophoresisnanoparticlesatom probe tomographyzirconiaelectrophoretic depositionSample preparation technique development for atom probe tomography of nanoparticlesText
