In this context, plasmonic nanoapertures in metallic films can not only be realized using CMOS compatible metals and processes, they can also serve to influence the wavelength-dependent device responsivities. Here, we investigate crescent-shaped nanoapertures in close proximity to Ge-on-Si PIN nanopillar photodetectors both in simulation and experiment. In our geometries, the absorption within the devices is mainly shaped by the absorption characteristics of the vertical semiconductor nanopillar structures (leaky waveguide modes). The plasmonic resonances can be used to influence how incident light couples into the leaky modes within the nanopillars. Our results can serve as a starting point to selectively tune our device geometries for applications in spectroscopy or refractive index sensing.}, language = {en} } @misc{SchlipfFischer, author = {Schlipf, Jon and Fischer, Inga Anita}, title = {Rigorous coupled-wave analysis of a multi-layered plasmonic integrated refractive index sensor}, series = {Optics Express}, volume = {Vol. 29}, journal = {Optics Express}, number = {22}, issn = {1094-4087}, doi = {10.1364/OE.438585}, pages = {36201 -- 36210}, language = {en} } @misc{TetznerFischerSkibitzkietal., author = {Tetzner, Henriette and Fischer, Inga Anita and Skibitzki, Oliver and Mirza, M.

We investigate the influence of the substrate orientation, Mn layer thickness and annealing parameters on the crystallographic orientation and magnetization of Mn5Ge3. It is shown that after millisecond range SPE, Mn5Ge3 films always have a preferred (100) orientation whether grown on Ge (001) or (111) substrates, which determines the orientation of the magnetization easy axis lying in the film plane along c axis independent of the layer thickness.
