Probing Phonons in Nonpolar Semiconducting Nanowires with Raman Spectroscopy

Figure 12

Second-order Raman spectra of Si nanowires TO phonons as a function of temperature. The numbers in the top panel (1, 2, 3, 4, 5, and 6) refer to Brillouin zone points 𝐗 , 𝐐 , 𝐒 𝟏 , 𝐖 , 𝐋 , and Γ , respectively. Temperature-dependent second-order Raman spectra of Si obtained using 632.8 nm laser excitation [113].
