The group "Physique des Nanostructures et Emission de Champ" develop a research program in nanoscience using field emission as the main experimental method.

the team, created in 2004, gather 7 permanent researchers, 1 PhD student and 3 post-docs.

• URGENT : post-doctoral position is available. This position is related to development of a Field Emission cathode for large screen application. See more details. contact : steve purcell

• Les nouveaux stages de master "M2 Recherche" pour l'année 2009-2010 ont été définis. Voir sur la page d'accueil du LPMCN.

• Acceptation des ANR PNano 2009 "SOS_Nanotubes" et "Mikado".

• Lancement de la "Plateforme Nanofils et Nanotubes Lyonnaise" qui regroupe les équipes qui travaillent sur les thématiques liées aux nanotubes et aux nanofils dans la région lyonnaise.

We report the observation of self oscillations in a bottom-up nanoelectromechanical system (NEMS) during field emission driven by a constant applied voltage. An electromechanical model is explored that explains the phenomenon and that can be directly used to develop integrated devices. In this first study, we have already achieved 50% dc/ac (direct to alternating current) conversion. Electrical self-oscillations in NEMS open up a new path for the development of high-speed, autonomous nanoresonators and signal generators and show that field emission (FE) is a powerful tool for building new nanocomponents.
