Probing Phonons in Nonpolar Semiconducting Nanowires with Raman Spectroscopy
Figure 11
Raman spectra at 632.8 nm for the Ge nanowire ( nm) for varying laser power levels (circles) at two different Ga droplet sizes (a) droplet size ~1 μm and (b) droplet size ~1 mm. The solid lines represent the least square fit (10) [80].
