Figure 6From: Synthesis and electrical property of metal/ZnO coaxial nanocablesPL spectra and XPS spectrum of the nanocables. (a) PL spectra of Ag/ZnO and Cu/ZnO nanocables on Si substrate. Each spectrum is normalized by its maximal intensity for easy comparison. (b) The XPS spectrum of Ag/ZnO nanocables. The high-resolution spectra for Ag species are shown in the inset.Back to article page
