Figure 3From: Thermal conductance calculations of silicon nanowires: comparison with diamond nanowiresThermal conductance of SiNW and phonon dispersion relation. Thermal conductance as a function of the diameter of SiNW without vacancy defects for several temperature. Inset is the exponent n of diameter dependence of thermal conductance for several temperature. (right) Phonon dispersion relation of 〈100〉 SiNW with 1.5 nm in diameter for the wave vector q. Here a=5.362 Å. Red and purple solid lines show weight functions in thermal conductance for 100 and 5 K.Back to article page
