Characterizing crystalline defects in single nanoparticles from angular correlations of single-shot diffracted X-rays

Christoph Bostedt, Alessandro Colombo, Giorgio Rossi

Characterizing and controlling the uniformity of nanoparticles is crucial for their application in science and technology because crystalline defects in the nanoparticles strongly affect their unique properties. Recently, ultra-short and ultra-bright X-ray ...

Three-dimensional imaging of integrated circuits with macro- to nanoscale zoom

Gabriel Aeppli, Manuel Guizar Sicairos, Christian David, Michal Odstrcil

The imaging of integrated circuits across different length scales is required for failure analysis, design validation and quality control. At present, such inspection is accomplished using a hierarchy of different probes, from optical microscopy on the mil ...

Advances in High-Speed Atomic Force Microscopy

Adrian Pascal Nievergelt

High-speed atomic force microscopy (HS-AFM) is a scanning probe technique capable of recording processes at the nanometre scale in real time. By sequentially increasing the speed of individual microscope components, images of surfaces can be recorded at up ...

Plasmonic Radiance: Probing Structure at the Ångström Scale with Visible Light

Olivier Martin, Benjamin Gallinet, Thomas Gerd Siegfried

Plasmonic modes with long radiative lifetimes combine strong nanoscale light confinement with a narrow spectral line width carrying the signature of Fano resonances, making them very promising for nanophotonic applications such as sensing, lasing, and swit ...

Interaction between liquid aluminium and solid iron Al-rich intermetallics formation

Guillaume Pasche

Intermetallic phases formation is one of the phenomena, which when coupled to thermal and mechanical strains leads to the premature wear of aluminium die casting tools made out of steel. This work focuses on two aspects of this wear problem. The first and ...

Atomic Force Measurements of Hydrophobic Interactions

Julien Perroset

This semester project comes within the scope of studies at the nanometre scale. The experimental techniques used in this work are related to atomic force microscopy, which gives a direct access to the topography and forces of the studied systems. The goal ...

Atomic-Layer Engineering of Oxide Superconductors

Davor Pavuna, Guy Joseph Günter Dubuis, Ivan Bozovic

Molecular beam epitaxy technique has enabled synthesis of atomically smooth thin films, multilayers, and superlattices of cuprates and other complex oxides. Such heterostructures show high temperature superconductivity and enable novel experiments that pro ...

Pd-functionalized MEMS resonator for hydrogen gas sensing

Jürgen Brugger, Luis Guillermo Villanueva Torrijo, Thomas Kiefer, Jonas Gustav Henriksson

This work presents the fabrication and characterization of a novel hydrogen-detecting micro-resonator based on the expansion of palladium (Pd) as it is exposed to hydrogen (H2) gas. The working principle of the device has been confirmed and it shows a stro ...
