Surface snow isotopic composition: Post-depositional processes in an alpine snowpack

Michael Lehning, Luca Bianchi, Yoann Nicolas Sadowski

Stable water isotopes are natural tracers allowing to reconstruct the history of a water parcel. They are used as climate proxies and to better understand the hydrological cycle. The snow isotopic composition is directly influenced by temperatures and atmo ...

Aerosol acidity and liquid water content regulate the dry deposition of inorganic reactive nitrogen

Athanasios Nenes, Spyros Pandis

Ecosystem productivity is strongly modulated by the atmospheric deposition of inorganic reactive nitrogen (the sum of ammonium and nitrate). The individual contributions of ammonium and nitrate vary considerably over space and time, giving rise to complex ...

Excitonic absorption and defect-related emission in three-dimensional MoS2 pyramids

Anna Fontcuberta i Morral, Luca Francaviglia, Marco Negri

MoS2 micro-pyramids have demonstrated interesting properties in the fields of photonics and non-linear optics. In this work, we show the excitonic absorption and cathodoluminescence (CL) emission of MoS2 micro-pyramids grown by chemical vapor deposition (C ...

Untersuchung der ökomorphologischen Wirksamkeit von Sedimentzugaben unterhalb von Talsperren [Assessment of the eco-morphological effectiveness of sediment augmentation downstream of dams]

Giovanni De Cesare, Christian Mörtl

The regulation of discharge and the retention of sediments in reservoirs disturb the natural water dynamics in residual flow stretches below reservoirs. However, a dynamic river morphology as well as near-natural hydrological hydrographs are fundamen ...

Development of microdevices for the in-plane thermoelectric characterization of deposited films

Stefano Mischler

Measuring the thermoelectric transport properties of a material is a prerequisite to determining its usefulness for application in waste heat recovery or cooling and the basis for devising improvement strategies. While well-established characterization met ...

An Experimental Setup for Heterogeneous Catalysis on Atomically Defined Metal Nanostructures

Jean-Guillaume De Groot

The main objective of this PhD thesis is to link the atomic scale structure to the catalytic properties of self-assembled nanostructures. The growth and characterization of these nanostructures was carried out in an ultra-high vacuum (UHV) chamber initiall ...

Vapor deposition of metal halide perovskite thin films: Process control strategies to shape layer properties

Christophe Ballif, Quentin Thomas Jeangros, Florent Sahli, Quentin Jean-Marie Armand Guesnay

Vapor-based processes are particularly promising to deposit the perovskite thin film absorber of solar cells. These deposition methods are up-scalable, involve a controlled solvent-free environment, have the ability to conformally coat rough substrates, in ...

Ammonia-assisted vapour transport deposition of formamidinium salts for perovskite thin films

Christophe Ballif, Quentin Thomas Jeangros, Florent Sahli, Léo Duchêne, Quentin Jean-Marie Armand Guesnay, Niccolo Salsi

Formamidinium (FA) cations commonly used in perovskite semiconductors tend to form sym-triazine when sublimed in vacuum, a process that hampers the deposition process. Here we find that ammonia, when used as a carrier gas for formamidinium halides transpor ...

ICRF modelling in 2D and 3D magnetic configurations using a hot plasma model

Jonathan Graves, Wilfred Anthony Cooper, Mike Machielsen

The generation of energetic trapped ions is important for experiments investigating their confinement in 3D magnetic fields, for plasma heating, for studies into unwanted drive of instabilities, and improved transport regimes. An effective way to generate ...

Fabrication of a Hydrogenated Amorphous Silicon Detector in 3-D Geometry and Preliminary Test on Planar Prototypes

Sylvain Dunand, Matthew James Large

Hydrogenated amorphous silicon (a-Si:H) can be produced by plasma-enhanced chemical vapor deposition (PECVD) of SiH4 (silane) mixed with hydrogen. The resulting material shows outstanding radiation hardness properties and can be deposited on a wide variety ...
