Can automotive MEMS be reliably used in space applications? An assessment method under sequential bi-parameter testing

Volker Gass, Maxime Auchlin, Olha Sereda

Commercial Off-The-Shelf (COTS) automotive inertial measurement units were subjected to severe accumulative stress conditions: thermal shocks (high temperature gradients), temperature cycling (low gradients) and mechanical vibration are combined in an A-th ...

Conformal Deposition of Conductive Single-Crystalline Cobalt Silicide Layer on Si Wafer via a Molecular Approach

Giovanni De Micheli, Olha Sereda, Pierre-Emmanuel Julien Marc Gaillardon, Tsung-Han Lin, David Baudouin

The realization of metal-semiconductor contacts plays a significant role in ultrascaled integrated circuits. Here, we establish a low-temperature molecular approach for the conformal deposition of a 20-nm Co-rich layer on Si (100) wafers by reaction in sol ...

Process influences on the structure, piezoelectric, and gas-barrier properties of PVDF-TrFE copolymer

Dragan Damjanovic, Yves Leterrier, Antonia Neels, Olha Sereda, Alex Dommann

The influence of annealing between the Curie transition and the melting point of solvent cast polyvinylidene fluoride trifluoroethylene copolymer films on the crystalline structure, mechanical and electrical properties, and oxygen permeability is investiga ...

Optimizing Parylene C Adhesion for MEMS Processes: Potassium Hydroxide Wet Etching

Philippe Renaud, Olha Sereda, Joanna Katarzyna Bitterli, Martha Liley, Herbert Keppner

Parylenes are used for a wide range of applications in microelectromechanical systems (MEMS) devices. However, their poor adhesion in a harsh liquid environment can limit the fabrication processes of complex MEMS and bioMEMS devices. Potassium hydroxide (K ...

Molecular Networks Based on Dative Boron-Nitrogen Bonds

Rosario Scopelliti, Kay Severin, Erin Sheepwash, Antonia Neels, Olha Sereda, Vincent Krampl

The BN connection: Crystalline and soft molecular networks can be constructed using dative BN bonds (see picture). The networks are obtained in a one-step, three-component reaction involving a triboronic acid, a catechol, and a bipyridyl linker. ...
