Probing Phonons in Nonpolar Semiconducting Nanowires with Raman Spectroscopy
Figure 9
Calculated Raman line shape of the 520 cm−1 band of Si nanowires subjected to laser inhomogeneous heating. The focal spot size is 1 μm in the micro-Raman focal plane. Results are calculated using (10) at the different peak temperatures indicated for (a) nm and (b) nm nanowires [44–46].
