Paper Abstract

We experimentally investigated Zinc oxide (ZnO) nanowires (NWs) on flat Si substrate and ZnO NWs on Au nanoislands attached on a Si substrate via hydrothermal technique, pursuing surface enhanced Raman scattering (SERS). Au nanoislands were formed by thermal annealing of a Au thin film deposited on Si substrate. ZnO NWs were then grown on two types of substrates (with and without Au nanoislands) and thermally annealed together. During the thermal annealing process, the ZnO NWs were coupled to Au nanoislands. After the thermal annealing, strong SERS enhancement was observed of ZnO NWs on Au nanoislands. Over 30 times enhancement in SERS was found when the initial Au layer thickness was 40 nm.
