Cathodoluminescence (CL) has long been used as a tool for the characterisation of semiconductors. Recently CL has been applied to the characterisation of a range plasmonic nanostructures, such as gold nanorods, tetrahedral and rings. Plasmonic CL allows for the optical properties of plasmonic nanostructures to be measured with high spatial resolution, this enables individual structures to be characterised without the need to fabricate a large arrays. In this talk I will demonstrate how plasmonic CL can be used to determine the optical properties of a range of plasmonic devices of different shapes and sizes using our CL setup at ANU.
Bio: Mark received his PhD in Physics at the University of Technology, Sydney in 2015, where his PhD studies focused on cathodoluminescence (CL) analysis of III-nitride materials. Mark joined the Australian National University (ANU) in 2015 as the Microanalysis Research Officer and SEM Process Engineer for the ANFF ACT Node, where he operates the FESEM-CL system. Mark's research interests include electron-beam processing of materials as well as the CL analysis of nano-materials and organic compounds
