UMR 3680 - Laboratory of Condensed Matter Physics (SPEC)

(homepage in French)

Welcome to the SPEC website

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) 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: Patrice Roche

Deputy Directors: Céline Fiorini and Myriam Pannetier-Lecoeur

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. To do so we employ a wide array of photoemission-based surface analysis techniques such as XPS, ARPES and PEEM as well as electron probes such as LEEM.
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].

Transition Vitreuse dans un Ferrofluide : En mettant des nanoparticules magnétiques en suspension dans un liquide, on obtient un ferrofluide. Ce dernier a les propriétés mécaniques d’un liquide et celles d’un matériau magnétique à température élevé (paramagnétisme). Les ferrofluides ont de nombreuses applications, par exemple dans les technologies aérospatiales, le transfert de chaleur ou la médecine.
