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 ...

Charged excitons in modulation-doped quantum wires

Marc-André Dupertuis, Benjamin Dwir, Elyahou Kapon, Daniel Oberli, Nicolas Moret

We report on the observation of negatively- and positively-charged excitons in the photoluminescence spectra of V-groove quantum wires. The. charged exciton binding energy increases with the strength of the quantum confinement. We demonstrate that fluctuat ...

Enhancement of the binding energy of charged excitons in disordered quantum wires

Klaus Leifer, Marc-André Dupertuis, Benjamin Dwir, Elyahou Kapon, Daniel Oberli, Nicolas Moret

Negatively and positively charged excitons are identified in the spatially resolved photoluminescence spectra of quantum wires. We demonstrate that charged excitons are weakly localized in disordered quantum wires. As a consequence, the enhancement of the ...
