We report for the first time the successful heteroepitaxial growth of Si(100) oriented layer on top of a 3C-SiC(001) seed. By using a post-growth modification of the 3C-SiC surface (pulse insertion of precursors during cooling), it led to a change in

Thick layer of polycrystalline silicon (poly-Si) grown by Atmospheric Pressure Chemical Vapor Deposition (APCVD) is still a reference material in a number of applications, despite the high thermal budget of this technique. This work presents a materi

International audience; This paper reports on the successful elaboration of fully (100) oriented SiC/Si/SiC/Si multi-stack using chemical vapor deposition. Si(100) heteroepitaxyon 3C-SiC(100) is identified as the critical step which is solved by puls

We fabricated and characterized record small microdisk resonators in thin (210 nm) 3C-SiC film grown on Si (100) substrate. It was found to support high quality factor whispering gallery modes at visible wavelengths. We demonstrated room temperature

Starting from the previously demonstrated twin-free 3C-SiC growth on 4H-SiC when using Ge pre-deposition treatment, this work focuses on the understanding of the growth mechanism that stands behind this result. Toward this end, short growth experimen

We report on the electrical characterization of the Metal-Oxide-Semiconductor (MOS) interfacerealized on in-situ Ge-doped n-type 4H-SiC epilayers grown by Chemical Vapour Deposition(CVD). In order to study the relevance of this novel material for MOS

The present communication focuses on the bilayer graphene formation on a Ge doped 4H-SiC surface. The 4H-SiC epilayer was grown by CVD with Germane (GeH4) as the dopant precursor. This easily leads to the formation of Ge islands as well as graphene o

The interaction of liquid Ge and Si droplets, deposited by CVD, on the surface of 4H-SiC single-crystals is studied. It was found that at 1500 °C Ge forms micrometric droplets while Si forms nanometric dots. While the Si dots do not seem to interact

We discuss the progress in integration of nanodiamonds with photonic devices for quantum optics applications. Experimental results in GaP, SiO2 and SiC-nanodiamond platforms show that various regimes of light and matter interaction can be achieved by

Particle size distribution at major on-road, roadside, and university-ground sites in Lebanon were studied in summer 2011. In a predominant old traffic fleet, it is shown that calculated PM2.5 mass emission factors (EFs) conform to those of heavy dut
