International audience; We have successfully synthesized and transferred graphene (Gr) monolayers on top of epitaxial mixed valence La0.7Sr0.3CoO3 (LSCO) thin films. Raman spectroscopy reveals that Jahn-Teller (JT) modes associated with the oxygen oc

International audience; Antimony-doped ZnO layers have been grown by metalorganic vapour-phase epitaxy on sapphire and ZnO substrates at high-temperature (950 °C) and low-pressure conditions (50 torr). Nitrous oxide and diethyl-zinc have been used a

We studied by Raman spectroscopy the effect of the variation of the thickness of the HfO2 layer in Si/SiO2/HfO2/Graphene heterostructures on the density of carrier transferred to graphene. Three thicknesses of the HfO2 layer equal to 30, 20, and 5 nm

We report the temperature dependence of the dielectric function, the exciton binding energy and the electronic transitions of crystallized ZnO thin film using spectroscopic ellipsometry (SE) and photoluminescence (PL). ZnO layers were prepared by sol

In this paper, we investigate stacked 2D graphene layers on hexagonal boron nitride (h-BN). The graphene is obtained by high-quality chemical vapor deposition (CVD) and transferred to the h-BN substrate. We focus our attention on annealing effect at

International audience; We propose a model taking into account the periodic spatial modulation of a doped gra- phene sheet conductivity when it is placed in the vicinity of a dielectric grating. We then compute the absorption and study the excitation

ZnSe layers were grown on ZnO substrates by the metal organic chemical vapor deposition technique. A new structure appeared at lower thicknesses films. The structural properties of the thin films were studied by the X-ray diffraction (XRD) and Raman

A Raman study of a twisted bilayer graphene grown by chemical vapor deposition (CVD) and transferred on SiO2 substrate is presented. The Raman spectra show the G and 2D peaks at 1582 cm−1 and 2683 cm−1 respectively. The presence of the interlayer
