Additional file 1: Figure S1. of Systematic Control of Self-Assembled Au Nanoparticles and Nanostructures Through the Variation of Deposition Amount, Annealing Duration, and Temperature on Si (111)

Raman spectra of bare Si (111) at room temperature. The emission was excited by a CW diode-pumped solid-state (DPPS) laser of a wavelength of 532 ± 1 nm with an output power of 120 mW. The signal was detected by a TE cooled CCD detector. a Full range between 154 and 1388 cm−1. Each Si peak is indicated with blue arrows. b Enlarged area between 260 and 700 cm−1 to show transverse acoustical (TA) mode peaks at 303 and 619 cm−1. The transverse optic (TO) peak at Γ appeared at 520 cm−1. The full width at half maximum of TO is 11.6 cm−1. Two TO peaks were also detected at 939 and 985 cm−1 [50]. Additionally, the peak at 619 cm−1 is also associated with Si [51]. (JPG 102 kb)
