New Nanoparticles Study Findings Have Been Reported by Investigators at City University of Hong Kong (The Effect of Plasmonic Nanoparticles on the Optoelectronic Characteristics of CdTe Nanowires)

By a News Reporter-Staff News Editor at Electronics Newsweekly -- A new study on Nanoparticles is now available. According to news reporting from Hong Kong, People's Republic of China, by VerticalNews journalists, research stated, "In this work, a simple strategy is proposed to improve the device performance of photodetector by modifying plasmonic nanoparticles onto the surface of semiconductors nanostructure."

The news correspondents obtained a quote from the research from the City University of Hong Kong, "Both experimental analysis and theoretical simulation show that the plasmonic metal nanoparticles (AuNPs) exhibits obvious localized surface plasmon resonance (LSPR) which can trap incident light efficiently, leading to enhanced photocurrents and improved performance of photoelectronic devices. It is also observed that the AuNPs modified CdTeNW photodetector exhibit apparent sensitivity to 510 nm light, to which pure CdTeNWs is virtually blind."

According to the news reporters, the research concluded: "What is more, after AuNPs decoration, the response speed of the photodetector is increased substantially from 6.12 to 1.92 s. It is believed that this result will open up new doors for manipulating light and further improving the efficiency of semiconductor nanostructures based optoelectronic devices."
