Low-Pressure Chemical Vapor Deposited Zinc Oxide Films

Laura Ding

Polycrystalline zinc oxide (ZnO) films, prepared by low-pressure chemical vapor deposition are investigated in this thesis. ZnO belongs to the class of transparent conductive oxide materials, as it is transparent to light from the visible to the near-infra ...

Atmospheric aerosols are one of the least understood components of the climate system and incur adverse health effects on susceptible populations. Organic aerosols can make up as much as 80% of atmospheric aerosols (Lim and Turpin

Taylor & Francis2013

Jets generated at chute ends move a potential scour zone away from the dam, and dissipate flow energy to reduce the scour. Usually, so-called flip buckets or ski jumps are provided to generate jets, yet they are rarely issued by deflectors. The application ...

Highly transparent ZnO bilayers by LP-MOCVD as front electrodes for thin-film micromorph silicon solar cells

Christophe Ballif, Matthieu Despeisse, Mathieu Gérard Boccard, Sylvain Nicolay, Grégory Bugnon, Laura Ding, Mustapha Benkhaira

ZnO bilayer films were deposited by a low-pressure metalorganic chemical vapor deposition technique in a single process step, by doping with boron only the nucleation stage of the growth. The resulting 2 pm thick layers are characterized by low free carrie ...

Response of an embedded block impacted by high-velocity jets

Matteo Paolo Elia Antonio Federspiel

The safety of dams is very often endangered by the formation of scour near the foundation as a result of high-velocity jet impact. These jets issue from appurtenant structures such as spillways and may impact in the immediate vicinity of the dam toe. The p ...

Experimental study on Scour due to simultaneous wall and impinging circular jet

Anton Schleiss

In this study the scour mechanism and the effect of some of the important parameters such as jet velocities, impinging jet distance from the upstream wall and tailwater depth on the longitudinal scour profile due to 3d simoultaneous wall and impinging jet ...

Terahertz Time-Domain Spectroscopy Study of the Conductivity of Hole-Transporting Materials

Jacques-Edouard Moser, Jan Cornelius Brauer, Verner Thorsmolle

Some redox-active ionic liquids, organic amorphous solids containing electron-donating moieties, and conductive polymers can efficiently transport positive electrical charges. These hole-conducting media find increasing applications in unconventional solar ...

Vertically moving micromirror for detectors in the mid infrared

Niels Quack

This paper presents continuative results on the design, fabrication and measurements of a vertically moving, electrostatically actuated micromirror, first shown at the IEEE MEMS 2007 [N. Quack, I. Züst, S. Blunier, J. Dual, M. Arnold, F. Felder, M. Rahim, ...

2008

The dissipation of energy of flood discharges from water releasing structures of dams is often done by plunging jets diffusing in water and impacting on the riverbed downstream. The construction of expensive concrete structures for energy dissipation can b ...

Onboard Flow Visualization in a Pelton Turbine Bucket

François Avellan, Alexandre Perrig

Flow visualizations using endoscopes in a 21-bucket single-injector reduced scale Pelton turbine are performed for 2 operating points. 2 types of visualizations are performed with a CMOS high-speed camera: (i) an onboard visualization of the flow in the bu ...
