UMR 3680 - Laboratory of Condensed Matter Physics (SPEC)

(homepage in French)

Welcome to SPEC!

We are the Condensed Matter Physics laboratory of IRAMIS (Saclay Institute for Radiation and Matter), a part of the French National Atomic Energy Commission (CEA: Commissariat à l'Energie Atomique) in Saclay, France.

SPEC is "Unité Mixte de Recherche" with the CNRS : UMR 3680.

At SPEC, we strive to be at the forefront of fundamental Condensed Matter Physics Research. Our research interests encompass a wide variety of subject matters ranging from nano-to macro-scopic scales and from the most fundamental aspects of science to applications, patents and technology transfer. SPEC is involved in many collaborations, within the CEA and at the national and international levels.

Director: François Daviaud

Deputy Directors: Patrice Roche and Céline Fiorini.

Research Activities

The SPEC is organized in 8 groups with scientific activities developing along 9 main research themes. To find out more please visit our research themes page and/or click on groups of your interests found below.

Groupe Photoemission, Photodiffraction and Spectromicroscopy : LENSIS People Publications Collaborations Contracts Jobs We are part of the Service of Condensed Matter (SPEC) in the IRAMIS institute of the French Atomic Energy Commission (CEA). We focus on the study of the electronic and chemical structure of functional oxides.
Aligned carbon nanotubes obtained using a surfactant bubble : ( French version) Recently Jean-Jacques Benattar and his co-workers at SPEC, CEA-Saclay have developed a simple and original technique to produce surfactant films containing nano-objects such as nanoparticles, nanowires etc. and to transfer such films onto solid substrates [1].
