The essential functionality of photonic and electronic devices is contained in thin surface
layers leaving the substrate often to play primarily a mechanical role. Layer transfer of …

Employing hydrothermal technique, undoped and nickel doped cerium oxide nanoparticles
(Ni doped CeO 2 NPs) are synthesized with different concentration of dopant (5 M%, 10 M …

RuO2 is one of the most important electrocatalyst materials as a key component of
dimensionally stable anode (DSA) for chlorine evolution reaction, because of the high …

We demonstrate for the first time a fully integrated electro-optic modulator based on locally
strained silicon rib-waveguides. By depositing a Si_3N_4 strain layer directly on top of the …

We report uniaxial tensile strains up to 5.7% along〈 100〉 in suspended germanium (Ge)
wires on a silicon substrate, measured using Raman spectroscopy. This strain is sufficient to …

Organic–inorganic hybrid perovskite materials exhibit a variety of physical properties.
Pronounced coupling between phonon, organic cations, and the inorganic framework …

Identification of nanoparticles and nanosystems into cells and biological matrices is a hot
research topic in nanobiotechnologies. Because of their capability to map physical …

Lately, germanium based materials attract a lot of interest as they can overcome some limits
inherent to standard Silicon Photonics devices and can be used notably in Mid-Infra-Red …

Germanium (Ge) is a group-IV indirect band gap semiconductor, and therefore bulk Ge
cannot emit light efficiently. However, the direct band gap energy is close to the indirect one …

We report the first realization of fully-released and relaxed Ge 1-x Sn x structures on Ge
substrate. The coefficients of Raman peak shift a and b due to the alloy disorder and strain …
