Lai Y.-C.Ho H.-C.Shih B.-W.Tsai F.-Y.CHUN-HWAY HSUEH2019-09-252019-09-25201801694332https://scholars.lib.ntu.edu.tw/handle/123456789/425028Surface-enhanced Raman scattering (SERS) substrate with a higher surface area, enhanced light harvesting, multiple hot spots and strong electromagnetic field enhancements would exhibit enhanced Raman signals. Herein, the Ag nanoparticle/ZnO nanowire heterostructure decorated periodic silicon nanotube (Ag@ZnO@SiNT) substrate was proposed and fabricated. The proposed structure employed as SERS-active substrate was examined, and the results showed both the high performance in terms of high sensitivity and good reproducibility. Furthermore, the Ag@ZnO@SiNT substrate demonstrated the self-cleaning performance through the photocatalytic degradation of probed molecules upon UV-irradiation. The results showed that the proposed nanostructure had high performance, good reproducibility and reusability, and it is a promising SERS-active substrate for molecular sensing and cleaning. ? 2018 Elsevier B.V.Atomic layer depositionPhotocatalystSilicon nanotubesSurface-enhanced Raman scatteringTextured substrateZnO nanowiresjournal article10.1016/j.apsusc.2018.01.0922-s2.0-85041426073https://www2.scopus.com/inward/record.uri?eid=2-s2.0-85041426073&doi=10.1016%2fj.apsusc.2018.01.092&partnerID=40&md5=3ad7db530eafaa41fe75fb665edb1058
