Abstract We report on a new route to grow epitaxial copper (Cu) ultra-thin films (up to 150 nm thick) at ambient temperature on Si(001) wafers covered with native oxide without any prior chemical etching or plasma cleaning of the substrate. It consis

Publikováno v: Beilstein Journal of Nanotechnology, Vol 8, Iss 1, Pp 440-445 (2017)

Scanning transmission electron microscopy (STEM) was successfully applied to the analysis of silicon nanowires (SiNWs) that were self-assembled during an inductively coupled plasma (ICP) process. The ICP-synthesized SiNWs were found to present a Si�

We report the photocatalytic efficiency of CuO nanowires covered with a thin TiO2 film, studied by dyes degradation in water. The CuO nanowires were synthesized on Cu foils by thermal oxidation. A subsequent TiO2 deposition (7, 15, 30, 50 nm thick) w

TiO2 nanotubes demonstrated to be a versatile nanostructure for biomaterials, clean energy and water remediation applications. However, the cost of titanium and the poor mechanical properties of the nano tubes hinder their adoption at large scale. Th

Formation of silicon nanocrystal chains induced via Rayleigh instability in ultrathin Si/SiO2 core/shell nanowires synthesized by an inductively coupled plasma torch process

Autor: Paola Castrucci, Marta Agati, Rajesh Pandiyan, My Ali El Khakani, Gitanjali Kolhatkar, Andreas Ruediger, Guillaume Amiard, Richard Dolbec, Simona Boninelli

Anew class of silicon (Si) nanohybrids is formed exploiting the Rayleigh instability experienced by Si nanowires (SiNWs) synthesized via inductively coupled plasma. These nanohybrids consist of three main categories of Si nanostructures: (i) core/she

Growth Mechanisms of Inductively-Coupled Plasma Torch Synthesized Silicon Nanowires and their associated photoluminescence properties

Autor: M. De Crescenzi, Guillaume Amiard, V. Le Borgne, Marta Agati, Richard Dolbec, Simona Boninelli, Paola Castrucci, M. A. El Khakani

Publikováno v: Scientific Reports

Ultra-thin Silicon Nanowires (SiNWs) were produced by means of an industrial inductively-coupled plasma (ICP) based process. Two families of SiNWs have been identified, namely long SiNWs (up to 2–3 micron in length) and shorter ones (~100 nm). SiNW

Publikováno v: 2016 IEEE Nanotechnology Materials and Devices Conference (NMDC).

For many decades, rare earths (REs) doped compounds have attracted considerable interest as emitting materials for displays and photonics applications. However, owing to the difficulty in achieving strongly efficient RE-doped emitting devices, the re
