Physique

Quantum diamond magnetometry for high-pressure sensing

High-pressure magnetometry can be implemented using nitrogen-vacancy (NV) colour centres in diamond. These atomic-like quantum systems can be fabricated at the tip of diamond anvils using nitrogen ion implantation. Due to their spin properties, NV…

Bottom‐Up Synthesis, Dispersion and Properties of Rectangular‐Shaped Graphene Quantum Dots

Abstract Carbon nanomaterials have attracted the attention of the scientific community for more than 30 years now; first with fullerene, then with nanotubes and now with graphene and graphene related materials. Graphene quantum dots (GQDs) are…

Real-time probing technique of domain wall dynamic in perpendicularly magnetized film

We present the study of a rarely mentioned method for measuring the magnetic domain wall velocity, which makes it possible to have a real-time probing of the domain wall movement in the perpendicularly magnetized thin film. We have compared this…

Use of magneto-optic Kerr effect for advanced magnetic imaging and domain wall real time propagation velocity measurements

Kerr imaging has been a powerful tool to view magnetic static structures, to study magnetic domain wall propagation or to get a hysteresis loop. We present here how Kerr effect can be used to go further. First, up to now, propagation of magnetic…

Evolution of Cu-In Catalyst Nanoparticles under Hydrogen Plasma Treatment and Silicon Nanowire Growth Conditions

We report silicon nanowire (SiNW) growth with a novel Cu-In bimetallic catalyst using a plasma-enhanced chemical vapor deposition (PECVD) method. We study the structure of the catalyst nanoparticles (NPs) throughout a two-step process that includes…

Metallic Plasmonic Nanostructure Arrays for Enhanced Solar Photocatalysis

Abstract Plasmon‐enhanced photocatalysis has emerged as a promising technology for solar‐to‐chemical energy conversion. Compared to isolated or disordered metal nanostructures, by controlling the morphology, composition, size, spacing, and…

Electric-field induced second harmonic generation responses of push–pull polyenic dyes: experimental and theoretical characterizations

The second-order nonlinear optical properties of four series of amphiphilic cationic chromophores have been investigated by means of electric field induced second harmonic generation and by combining molecular dynamics and quantum chemical…
