Probing Phonons in Nonpolar Semiconducting Nanowires with Raman Spectroscopy
Figure 15
Thermal conductivity of individual Si nanowire. Symbols: experimental data [115]. Solid lines: elastic continuous model (ECM) which considers the optical phonons decay into acoustic phonons as acoustic phonon generation rate. Dashed lines: theoretical results obtained from ECM without accounting for the optical phonon decay.
