The Nanophotonics group provides access to state-of-the-art microscopy equipment and assistance required for the range of charged particle (CPM) and light microscopy techniques. Our activities of imaging and analysis range from single nanoparticles to large-scale electronic devices for both academic and industrial projects. Our equipment is used for advanced nano-resolution imaging, chemical and morphological analysis, failure analysis, and fabrication for materials science and life sciences.

 

 

Imaging facilities

Orion NanoFab lab

A Zeiss Orion NanoFab facility consisting of a multibeam ion microscope dedicated to micro- and nanofabrication and imaging.

Technological highlights:

  • Imaging resolution: higher than 0.5 nm
  • Three ion beams (Helium, Neon and Gallium) integrated in one instrument
  • Charge compensation: by an electron flood gun
  • Fabrication tools: structuring by Ion-beam milling and by ion-beam chemical decomposition in a sub-10 nm to µm range
  • Fabrication Software: nano-patterning and visualisation engine (NPVE)


Example case studies

a. Nephilla Madagasariensis silk–sectioning and imaging
b. Hierarchical Au Needle Clusters on Highly Active TiO2 Thin Film
c. Human Adenovirus attached to magnetic beads

Nano Optics Lab

We utilise laser scanning microscopy and time-resolved spectroscopy to trace dynamics in materials that detect light emission phenomena occurring in extremely short periods. Within this field, we monitor and analyse the temporal decay of organic materials and devices' photo- and electroluminescence signals with sub-nanosecond time and diffraction-limited spatial resolution to improve the performance and device lifetime. Here, we investigate degradation processes or the interaction of thin organic layers and fibres with nanostructured substrates.


Cleanroom facility

Furthermore, a range of Scanning Electron and Atomic Force Microscopies is available through the C-MAC cleanroom facility. A full list of the cleanroom equipment, including details on the facility, can be found at https://www.sdu.dk/en/forskning/cmac

 

Recent projects

PlastTrack – a technological platform for tracing plastics in our seas
In the PlastTrack Interreg 6a project, we collaborate across the Danish-German border, bringing in our expertise to develop an imaging toolbox to monitor the transformation and degradation of micro- and nanoplastics in the environment.
We aim to prevent further uncontrolled releases of micro- and nanoplastics by providing tools that track the path of plastic waste and support the development of environmental product declarations. We will develop the technological platform, automate the detection and digitise the analysis of micro- and nanoplastics.
Funding: Deutchalnd-Danmark Interreg 6a programme
