Oxygen assisted focused electron beam induced deposition of silicon dioxide

Alexandre Perentes

Focused Electron Beam Induced Deposition (FEBID) is a rapid prototyping technique for the investigation, production and modification of 2 and 3-D nanostructures. The process takes place at room temperature, in the high-vacuum chamber of a Scanning Electron ...

Confining the sampling volume for Fluorescence Correlation Spectroscopy using a sub-wavelength sized aperture

Patrik Willi Hoffmann, Marcel Leutenegger, Alexandre Perentes, Theo Lasser, Olivier Martin

For the observation of single molecule dynamics with fluorescence fluctuation spectroscopy (FFS) very low fluorophore concentrations are necessary. For in vitro measurements, this requirement is easy to fulfill. In biology however, micromolar concentration ...

Fabrication of arrays of sub-wavelength nano-apertures in an optically thick gold layer on glass slides for optical studies

Benjamin Dwir, Patrik Willi Hoffmann, Ivo Utke, Marcel Leutenegger, Alexandre Perentes, Theo Lasser

We report on the fabrication of two-dimensional arrays of nano-optical apertures in gold layers by electron beam lithography (EBL) on a transparent glass substrate. 30 x 30 μ m(2) large arrays of high aspect ratio sub-wavelength cylinders (400 nm diameter ...
