High resolution nc-AFM and KPFM imaging of molecular assemblies at low temperature, Imagerie à haute résolution des assemblages moléculaires par nc-AFM et KPFM à basse température

Natalia Turek

The progress of non-contact Atomic Force Microscopy (nc-AFM) in the last decade enabled studying the structural and electronic properties of molecules at the submolecular scale. The process of tip functionalization relying in attaching single atoms or molecules to the tip apex demonstrated an…, Le progrès important de la microscopie à force atomique sans contact (nc-AFM) au cours de la dernière décennie a permis d'étudier les propriétés structurelles et électroniques des molécules à l'échelle sub-moléculaire. Le processus de fonctionnalisation de la pointe, qui consiste à…

Caractérisation et modélisation de composants GaN pour la conception de convertisseurs statiques haute fréquence, Characterization and modeling of GaN power devices for high freuency power converters design

Loris Pace

La montée en fréquence de commutation des transistors de puissance à base de Nitrure de Gallium (GaN) présente une avancée technologique conduisant à la réduction de la taille, du poids et du volume des systèmes de conversion de l’énergie. En effet, les propriétés physiques des transistors de type…, The high frequency operation of GaN power transistors is of great interest in order to reduce size, weight and volume of power converters. Indeed, GaN HEMT power transistors show very good physical properties for the development of high frequency power converters. Within the constant rise of the…

Iuliacumite: a novel two-dimensional chemical short range order in a wurtzite single monolayer InAs 1-x Sb x shell on InAs nanowires

Michael Schnedler, Tao Xu, Isabelle Lefebvre, Jean-Philippe Nys, S.R. Plissard, Philippe Caroff, Maxime Berthe, Holger Eisele, Rafal E Dunin-Borkowski, Philipp Ebert, B. Grandidier

A chemical short range order is found in single monolayer InAs1-xSbx shells, which inherit a wurtzite structure from the underlying InAs nanowire, instead of crystallizing in the energetically preferred zincblende structure. The chemical order is characterized by an ordering vector in [0001] and an…

Hearing the shape of a chemical reactor with a deep network of swarms

Nicolas Lobato-Dauzier, Leo Cazenille, Nathanaël Aubert-Kato, Alexis Vlandas, Teruo Fujii, Anthony J Genot

Biological swarms-from the simplest bacteria to large populations-compute the solution of geometrical problems for their growth and survival. In order to engineer synthetic swarms, it is of interest to understand how biological swarms relate space and time to sense their geometry. Here we propose a…
