The impact of the deposition of a TiN electrode on the high-k oxide HfO"2 has been investigated, focussing on the dielectric band gap. After the gate elaboration, a non-destructive approach combining Spectroscopic Ellipsometry (SE), Reflection Electr

In standard diffraction experiments, ensembles of objects are characterized yielding averaged, statistical properties (meaningful only if the ensemble is monodisperse). Focused x-ray beams are used here to localize single nanostructures, identifying

Epitaxial metal/oxide based magnetic tunnel-junctions (MTJ) are valuable model systems to investigate the influence of the crystallinity of individual layers on the magnetic properties. We have non-destructively studied the effect of the optical lith

Two series of oxynitride glasses, RE–Si–Mg–O–N ( M = Mg , Al ; RE = La , Lu), have been studied by X-Ray photoelectron spectroscopy (XPS). The oxygen 1s photoelectron lineshape reveals a striking difference depending on the rare earth, both i

The present study focuses on the growth mode and interface reactivity of the prototypical Co/α-Fe2O3(0 0 0 1) ferromagnet/antiferromagnet interface. The knowledge of these properties is essential to improve our understanding of the exchange bias phe

The aim of the present work was to evaluate the ability of reflection electron energy loss spectroscopy (REELS) as a non-destructive method to obtain depth profiles of dielectric constants, in a complementary way to transmission electron energy loss

In this paper, a detailed study of the magnetic behaviour particularly at the Verwey transition is presented for some stoichiometric magnetite samples, as a function of their shape (film/bulk) and crystalline structure (single/polycrystal). Travellin

A new pair of Kramers–Kronig (KK) dispersion relationships for the transformation of surface energy loss function Im[−1/(e + 1)] has been proposed. The validity of the new surface KK transform is confirmed, using both a Lorentz oscillator model a
