Representative (a) TEM and (b) high resolution TEM images of the codoped SiNWs synthesized by laser ablation of and targets.
(a) Si optical phonon peaks and the B local vibrational peaks observed for B-doped SiNWs (B: 10 at%), codoped SiNWs (B; 10 at%, : 5 mol%), undoped SiNWs, and bulk Si. (b) Dependence of Fano broadening and the B local vibrational peak on the content of in the ablation targets. The micro-Raman scattering measurements were performed at an excitation power of 0.02 mW at RT.
(a) ESR spectra observed for P-doped SiNWs and codoped SiNWs synthesized using and targets. (b) Raman spectrum observed for the codoped SiNWs.
(a) Dependence of the ESR signal intensity of the conduction electrons and the intensity of the B local vibrational peak on the content of B in targets.
