Fabrication of glass suspended microchannel resonators

The goal of this project was to study if the fabrication of glass suspended microchannel resonators was possible. Through trial and error, the process parameters were determined, starting from the ideal dose in the dry etching process. The ideal size was d ...

Vapor Transport Deposition of Methylammonium Iodide for Perovskite Solar Cells

Christophe Ballif, Quentin Thomas Jeangros, Florent Sahli, Cédric Bucher, Aymeric Michel Schafflützel, Björn Niesen, Léo Duchêne, Quentin Jean-Marie Armand Guesnay, Niccolo Salsi, Nathanaël Miaz

Vapor-based processes are promising options to deposit metal halide perovskite solar cells in an industrial environment due to their ability to deposit uniform layers over large areas in a controlled environment without resorting to the use of (possibly to ...

Comparison of high density and nitrogen seeded detachment using SOLPS-ITER simulations of the tokamak a configuration variable

Basil Duval, Holger Reimerdes, Christian Gabriel Theiler, Kevin Henricus Annemarie Verhaegh, Mirko Wensing, Hugo De Oliveira, Lorenzo Martinelli

First of a kind SOLPS-ITER simulations on tokamak a configuration variable (TCV) that include nitrogen have been performed to model recent nitrogen seeded detachment experiments. Based on spectroscopic measurements, a nitrogen recycling coefficient R-p(N) ...

Plasma-enhanced atomic layer deposition of nickel nanotubes with low resistivity and coherent magnetization dynamics for 3D spintronics

Anna Fontcuberta i Morral, Dirk Grundler, Julien Gay, Simon Robert Escobar Steinvall, Maria Carmen Giordano

We report plasma-enhanced atomic layer deposition (ALD) to prepare conformal nickel thin films and nanotubes by using nickelocene as a precursor, water as the oxidant agent and an in-cycle plasma enhanced reduction step with hydrogen. The optimized ALD pul ...
