FIG. 1.

(Color online) (a) Angle-dependent Raman spectroscopy is measured at different angles between the laser polarization and the rod length ( axis). The inset shows a schematic diagram of the Raman scattering configurations measured on a single freestanding nanorod. (b) Normalized integrated intensity in all phonon modes. Scattered symbols are experimental data and solid lines are theoretical fitting.

FIG. 2.

(Color online) Stokes and anti-Stokes lines were measured to estimate the nanorod temperature with various laser power densities. The estimated temperatures of the nanorod from calculations are plotted in the inset.

FIG. 3.

Micro-Raman spectra were measured from a single freestanding GaN nanorod and a compact GaN thin film. A prominent peak at is contributed from the surface vibrational mode of GaN nanorod. All samples were measured in the scattering configuration to obtain all main Raman peaks.
