The objective of the NANOIS project is to shape embedded nanostructures by swift heavy ions to create antenna-like features with highly enhanced plasmonic activity. The ion beam shaping of nanoparticles by elongating them in the direction of the passing swift heavy ions, was discovered 12 years ago, and has been studied extensively since then. However, this far the studies have been limited almost solely to reshaping of spherical particles by a large number of ion impacts. In the NANOIS project, we will use single high-energy ion impacts on nanostructures with different geometries (rods, disks, and platelets) and sizes to create smaller nanoantennas protruding from the structures. The created nanoantennas have high plasmonic activity that can benefit many different optical techniques, such as surface-enhanced Raman spectroscopy. The used experimental techniques will allow scaling of the technology to wafer-scale sizes.

The consortium is formed from a simulation group (UH) and an experimental group (JYU) working in close collaboration. The analysis of the shaping mechanism in 1D and 2D structures requires both the simulation work, which is the only tool that can consider the atom dynamics on the picosecond timescale, and the experiments, allowing quick testing of new nanostructure and matrix materials, for which the simulations have not yet been verified. Also optical measurements of plasmonic activity are crucial for developing a model that allows predicting which irradiation conditions to use to achieve a desired functionality. The materials tested include several different plasmonically active metals within difference oxide and nitride insulators.

The studies will be carried out with a wide range of experimental tools available in JYU Accelerator laboratory and Nanoscience Center, as well as high-performance computing methods utilizing the massive capacity available in the national CSC and FGCI computing infrastructures.
