Multimodal Scanning Microwave and Electron Microscopy for nanoscale measurements under vacuum

Petr Polovodov, Clément Lenoir, Christophe Boyaval, Kamel Haddadi, Didier Théron

A Near-Field Scanning Microwave Microscope (NSMM) is operated inside a Scanning Electron Microscope (SEM). This experimental setup combines atomic force microscopy, microwave measurements (potentially up to 67 GHz), and SEM. With the piece of equipment, we investigate the potential benefits of...

Optimization of the melt and quench behavior of phase-change RF switch to improve power handling

Corentin Mercier, Bruno Reig, Stéphane Monfray, Emmanuel Dubois, Alain Fleury, Frederic Gianesello, Vincent Puyal, Ismaël Charlet, J. Lugo-Alvarez, Clémence Hellion, Marjolaine Allain, Joey Denizart, J.F. Robillard

This paper presents two methods to improve the reliability and the melting/quench behavior of phase change materials (PCM) used in radiofrequency (RF) switches. Results show benefits of the addition of an aluminum nitride heat spreading layer and the reduction of the distance between the substrate...

A Versatile Balun Based on a Power Divider Topology

Lucie Jeannin, Larbi Boukhezar, Olivier Occello, Loïc Vincent, Guillaume Ducournau, Marc Le Roy, André Pérennec, Philippe Ferrari

This paper presents an original balun concept based on a power divider topology. The proposed concept simplifies the design compared to a Marchand balun by eliminating the interconnection problem between the two couplers forming the Marchand balun. Furthermore, the proposed concept is highly...

Optical and electronic properties of colloidal CdSe nanoplatelets and related heterostructures, Propriétés optiques et électroniques des nanoplaquettes colloidales de CdSe et des hétérostructures associées

Huu Thoai Ngo

Advances in colloidal chemistry have enabled the synthesis of various colloidal nanocrystals (NCs) such as quantum dots (QDs), quantum rings (QRs), nanoplatelets (NPLs) and nanorods (NRs), characterised by quantum confinement effects. Among them, colloidal NPLs (e.g. CdSe, PbSe) stand out for their..., Les progrès en chimie colloïdale ont permis la synthèse de divers nanocristaux colloïdaux (NCs) tels que les boîtes quantiques (QDs), les anneaux quantiques (QRs), les nanoplaquettes (NPLs) et les nanobâtonnets (NRs), caractérisés par des effets de confinement quantique. Parmi eux, les NPLs...

Two-Frequency Laser Source Stabilized on a Single Fiber Interferometer for Low Phase Noise and Frequency-Stable Millimeter-Wave Generation

Jose-Javier Fernandez-Pacheco, Loïc Morvan, Daniel Dolfi, Guillaume Ducournau

The constant evolution of wireless communication systems, where increasingly greater capacity of data volume management is required, has led many researchers to explore the millimeter-wave terahertz bands (0.1-10 THz). The generation of data signals at such frequencies often rely on optical...

Impact of cavity shape on thermal accelerometer parameters

Valentin Toulme, Soukaina Ben Salk, Marc Faucher, Philippe Combette, Alain Giani

Many kinds of accelerometers have been developed for measuring vibration and shock in different application. Thermal accelerometer, developed for the last fifteen years, present good advantages since it works on thermal convection with no moving parts and could survive very high levels of shock up...
