Electronic and Optical Properties of Semiconductor Quantum Dots

This thesis is devoted to theoretically study the systems of single quantum dots (QDs) embedded in various photonic nanostructures, in close relation with experimental data. The word single is essential: due to their nanometer size, QDs have mainly been st ...

Single Molecule Sensing

Claudio Dellagiacoma

Living organisms consist of cells, the elementary components of which are proteins providing cellular structures and functionality. Nowadays, proteins of the size of one to a few tens of nanometers can be efficiently monitored by fluorescence microscopy an ...

100 mm dynamic stencils pattern sub-micrometre structures

Jürgen Brugger, Andreea Veronica Savu, Shenqi Xie

Dynamic stencil lithography uses a moving shadow-mask to draw patterns by having directionally evaporated material deposited through the stencil apertures onto the substrate. Sub-micrometre, two- dimensional patterning is demonstrated at full 100 mm wafer ...

Hybrid polymer microlens arrays with high numerical apertures fabricated using simple ink-jet printing technique

Jürgen Brugger, Edoardo Charbon, Vahid Fakhfouri, Dmitri Boiko, Joo Yeon Kim, Nils Benedict Brauer

Microlens arrays fabricated by a direct ink-jet printing of UV-curable hybrid polymer are reported. A periodic pattern of polymer drops was ink-jet printed on the surface-treated glass substrate and cured in the UV-light. Using this simple technique, we de ...

An old tool and a new challenge for depicting antenna array radiation patterns

Juan Ramon Mosig

This paper is intended for teachers and students dealing with antenna engineering. Graphical tools have historically been used for illustrating many basic features of radiation patterns, such as the position and number of secondary lobes, null angles, and ...

Measuring amplitude and phase of light emerging from microstructures with HRIM

Hans Peter Herzig, Toralf Scharf, Myun Sik Kim

Ultra high-resolution measurements of amplitude and phase fields emerging from fine period amplitude gratings are presented and discussed. In the axial direction periodically repeated features are found, whose origins are the Talbot effect within the Fresn ...

Huygens-Fresnel diffraction and evanescent waves

Demetri Psaltis

Based on a modified Huygens-Fresnel principle valid in the near field, we analytically verify the exponential wave decay of evanescent waves. This field decay along the propagation direction can be considered as the result of interference between elementar ...

Tunable Infrared Absorption and Visible Transparency of Colloidal Aluminum-Doped Zinc Oxide Nanocrystals

Raffaella Buonsanti, Anna Llordes Gil

Plasmonic nanocrystals were attracting a lot of attention both for fundamental studies and different applications, from sensing to imaging and optoelectronic devices. Transparent conductive oxides represent an interesting class of plasmonic materials in ad ...

Comparison between SOFI and STORM

Theo Lasser, Stefan Geissbühler, Claudio Dellagiacoma

A straightforward method to achieve super-resolution consists of taking an image sequence of stochastically blinking emitters using a standard wide-field fluorescence microscope. Densely packed single molecules can be distinguished sequentially in time usi ...

High fidelity transfer of nanometric random textures by UV embossing for thin film solar cells applications

Christophe Ballif, Franz-Josef Haug, Corsin Battaglia, Jordi Escarre Palou, Karin Söderström

We investigate the transfer of random nanostructures commonly used in thin film silicon solar cells onto inexpensive substrates, such as glass or flexible polyethylene sheets. Morphological and optical analyses of masters and replicas show the successful t ...
