Study Results from Chinese Academy of Science Provide New Insights into Nanofibers (Influences of different interdigital spacing on the performance of UV photodetectors based on ZnO nanofibers)

By a News Reporter-Staff News Editor at Science Letter -- Investigators publish new report on Nanofibers. According to news reporting from Beijing, People's Republic of China, by NewsRx journalists, research stated, "Zno nanofibers (NFs) were fabricated by using an electrospinning method and characterized by meansof X-ray diffraction (XRD), scanning electron microscope (SEM) and UV-vis absorption spectrum. Auelectrodes with different interdigital spacings were deposited on the ZnO NFs to form devices."

The news correspondents obtained a quote from the research from the Chinese Academy of Science, "The photoresponse of the devices was studied and compared. Under the irradiation of 260 nm UV light with an8.8 mu Wcm(-2) irradiation-intensity, the photocurrent is 9.6 mu A for device S1. At 5 V bias, device S1 gets the highest responsivity of 287 A/ W, which has an UV/ vis rejection ratio about three orders of magnitude. The physical mechanism of the devices was also discussed."

According to the news reporters, the research concluded: "The experimental results suggest that theresponsivity of ZnO NFs UV photodetectors is obviously increasing with the reduction of the interdigital spacing."
