Abstract :
Surface enhanced Raman scattering is studied in nanostructures with GaN and ZnO nanocolumns. Features related to optical phonons of nanocolumns are observed in the Raman spectra of both free-standing GaN and ZnO nanostructures. Strong enhancement of the Raman scattering intensity by surface optical phonons in GaN and ZnO nanocolumns is observed by deposition of silver clusters onto the nanostructure surfaces.
