Laboratory of Physics and Chemistry of Surfaces and Interfaces
logo_tutelle 

On January 6, 2014, the teams of the SPCSI (Division of Physics and Chemistry of Surfaces and Interfaces) have been officially associated to  IRAMIS/NIMBE (chemists) and IRAMIS/SPEC (physicists).

Since july 2000 to the end of 2013, the SPCSI (Physics and Chemistry of Surfaces and Interfaces Laboratory) has been a research unit for the studies of basic properties of surfaces and interfaces and their potential applications. This Laboratory was part of to the Research Division on Atoms, Molecules and Condensed Matter (DRECAM) then IRAMIS (Saclay Institute of Matter and Radiation) within the Department of Matter Sciences (DSM) of the CEA (French Atomic Energy Commission).

Gathering chemists and physicists, the SPCSI was equipped with a powerful set of devices for characterization at the atomic scale of surfaces: an XPS Kratos and a platform of equipments  (STM / AFM - LEEM / PEEM - XPD) to investigate surfaces under ultrahigh vacuum, that the NIMBE and SPEC teams continue today to use successfully.

Les techniques de diffraction permettent de sonder l'ordre dans la matière. Pour ceci, on fait interagir une onde dont la longueur d'onde λ est comparable à la taille du motif cristallin élémentaire de l'échantillon. Ce peut être une onde électromagnétique (rayons X, lumière Laser) ou des particules (électrons, neutrons ou des atomes d'hélium).

Microscopies électroniques TEM, MEB et LEEM/PEEM
Plusieurs types de microscopies électroniques sont disponibles à l'IRAMIS : - Microscopie à transmission (TEM : Transmission Electron Microscope), qui permet d'atteindre les plus hautes résolutions par diffusion/difffraction d'un faisceau d'électrons à travers un échantillon ultra-mince - Microscopie MEB et MEB-FEG (SPAM et SIS2M), ou microscopie à balayage, pour laquelle un faisceau d'électrons balaye la surface  de l'échantillon permettant d'obtenir une image de sa surface.

Development of novel XPEEM (spatial,momentum and energy resolved)

L'éclairement, par un rayonnement suffisamment énergétique, de la surface d'un matériau peut conduire à l'émission d'électrons dont la spectroscopie (étude en énergie) apporte des informations sur la composition de la surface étudiée.

Electrical boundary conditions : « Back to the Group page « Back to the Oxides page   The new physics emerging from two-dimensional films in the limit of a few unit cells has a host of exciting applications. However, understanding the ferroelectric properties of such engineered thin film systems requires taking into account not only the material but also its interfaces with electrodes, substrates or atmosphere; in other words, the electrical boundary conditions.
Screening : « Back to the Group page « Back to the Oxides page   Surface polarization charge in ferroelectric (FE) materials can be screened by a variety of mechanisms: intrinsic (charge carriers or defects in the bulk), extrinsic (chemical environment or adsorbates), domain ordering, or even a combination of the above. Chemisorption of OH- and protons can lead to important changes in the electrical boundary conditions and water film can play an active role in domain switching.

Fracture is a phenomenon of everyday life: it is observable at all scales of condensed matter, from the atomic scale (in nanostructures) to the scale of our planet marked by fractures in the continental plates. But, can we find a unifying model to describe the phenomenon? The dynamics of fracture is complex.
