Abstract
Indium phosphide (InP) nanowire networks coated with gold were characterized by Raman spectroscopy. First, InP nanowire networks were grown via metal organic chemical vapor deposition (MOCVD) on silicon substrates with gold catalyst. Subsequently, gold was deposited by thermal evaporation on the grown InP nanowire networks. Different nominal thicknesses of gold were deposited, and then the goal coated InP nanowire networks were annealed in vacuum. Raman spectroscopy was used to study the dependence of InP phonon modes on the thickness of the gold coating. The study shows the gold coating decreases the longitudinal optical phonon mode signal of InP as the thickness increases.
