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…

Efficient and all-carbon electrical readout of a NV-based quantum sensor

The spin readout of an ensemble of nitrogen-vacancy (NV) centers in diamond can be realized by a photoconductive detection that is a complementary method to the optical detection of the NV electron spin magnetic resonance. Here, we implement the…

Investigation of Rod‐shaped Single Graphene Quantum Dot

In recent years, there has been a resurgence of interest in graphene quantum dots ( i.e. large polycyclic aromatic hydrocarbons) in particular due to their interesting properties as single quantum emitters. Here, we report on a thorough study of a…
