Modeling of a quantum cascade laser operating at 1 THz

Olivier Bonno, Jean-Luc Thobel, François Dessenne

A design of a quantum cascade laser operating at 1 THz is proposed and studied by means of ensemble Monte Carlo simulation. Starting from a resonant-phonon structure working at 2.1 THz [B. Williams, S. Kumar, Q. Hu, J. Reno, Electron. Lett. 40 (7) (2004) 431], a refinement is proposed in order to…

Design of a X-band GaN oscillator: from the low frequency noise device characterization and large signal modeling to circuit design

Geoffroy Soubercaze-Pun, Jean-Guy Tartarin, Laurent Bary, Jacques Rayssac, E Morvan, B Grimbert, Jean-Claude de Jaeger, Jacques Graffeuil

Although GaN technologies were initially developed for solid state source amplifiers, it was recently demonstrated that AlGaN/GaN HEMT transistors were also suitable for low noise applications such as LNA. The frequency synthesis is not yet widely explored for these technologies. In this paper the…

Characterization of structural defects in (110) GaN films grown on (102) sapphire substrates

P. Vennegues, F. Mathal, Z. Bougrioua

The microstructure of (11‐20) GaN films grown on (1‐102) sapphire substrates is studied by transmission electron microscopy. The predominant defects emerging at the surface of a 1‐2 μm thick layers are basal stacking faults of I1 type (1/6<20‐23> displacement vector). These defects are either…

Hierarchical Graph-Based Sizing for Analog Cells Through Reference Transistors

Ramy Iskander, Marie-Minerve Rosset-Louërat, Andreas Kaiser

In this paper, an algorithm for automatic sizing and operating point computation of hierarchical knowledge-based analog cells is presented. The algorithm assumes that an analog cell is described as a hierarchy of devices and modules inside our dedicated framework CAIRO+. Within devices, the concept…

Design and experimental verification of backward wave propagation in periodic waveguide structures

Jorge Carbonell, Luis J. Rogla, Vicente Boria, Didier Lippens

Experimental results for the demonstration of backward-wave or double-negative (DNG) propagation in waveguide technology combining inductive windows and split-ring resonators are presented and discussed in depth. A novel segmented prototype has been designed, fabricated, and measured, thus allowing…

Capillary filling of miniaturized sources for electrospray mass spectrometry

S. Arscott, Matthieu Gaudet, Martin Brinkmann, Alison Ashcroft, Ralf Blossey

Capillary slot-based emitter tips are a novel tool for use in electrospray ionization–mass spectrometry of large biomolecules. We have performed a combined theoretical and experimental study of capillary filling in micron-sized slots with the aim of developing a rational design procedure for…
