In work led by McKenzie Fellow, Dr Nitu Syed, researchers from the ARC Centre of Excellence for Transformative Meta-Optical Systems, have developed a gas sensor using atomically thin transparent two-dimensional (2D) tin dioxide film. The material has a thickness of only 2 nanometres which is 50000 times thinner than a paper. Reducing the thickness to […]
Work led by Tim Davis is featured as an Editor’s Pick in the latest Optics Express – link here. We show that by extracting structural information from transmission electron microscopy data, including characteristic disorder parameters, good agreement with spectral specular and non-specular reflectance measurements can be obtained.
The Australian Research Council Centre of Excellence for Transformative Meta-optical Systems (TMOS) is currently seeking expressions of interest from prospective PhD research higher degree and MSc coursework students. Students should send an expression of interest to Professor Ken Crozier and/or Professor Ann Roberts – a list of potential projects can be found here. Applications need […]
In work just published in Materials Today Advances, members of the group, led by Laura Ospina-Rozo, report new results into the optical and near-infrared properties of beetle elytra. We showed that some scarab beetles use composite, non-chiral structures to reflect light where the elytra consist of a broadband reflective structure overlain by a green filter. […]
Members of the Melbourne node, Dr Wendy Lee, Dr Lukas Wesemann and PhD student Shaban Sulejman attended the official launch of the ARC Centre of Excellence for Transformative Meta-Optical Systems (TMOS) at ANU on the 28th September. The launch was attended by Australian Research Council Chief Executive Officer Ms Judith Zielke, ANU Vice Chancellor Prof. […]
Work led by Lukas Wesemann published in ACS Photonics reports the use of a metasurface for generating pseudo-3D images of phase objects. His subsequent article in The Conversation discusses its potential application to disease detection.
A new paper led by PhD student Niken Priscilla reveals an intriguing device which exhibits a different colour variation when observed from either side. Unlike previous research the structure involves four simple nanoscale thickness layers of silica, silver and chromium. The research has been published in Advanced Photonics Research – link here.
Dr Alexander Wood is the recipient of the 2021 Woodward Medal in Science and Technology for his suite of publications in Nature Physics, Science Advances and Physical Review Letters concerning how physical rotation can be used as a tool for control and measurement of a quantum system. The Woodward Medal was established to reward outstanding […]
Faris Shahidan has led new work appearing today in Optics Express. Using nanoimprint lithography we show that it is possible to generate vivid colouration without the requirement for polarised light. Embossed polymers are coated with a variety of metals permitting an investigation of the role of the choice of metal. This work opens up the […]
Congratulations to Dr Shahidan whose PhD was awarded on 31 August! From his citation his contributions to the field involved the investigation of novel approaches to generating nanostructured surface colouration. He showed that nanoimprint lithography can produce complex three-dimensional nanostructures over large areas and at scale critical to adoption of structural colour technologies. His work […]
