Figure 2

Thermal conductivity of large-diameter SiNWs (approximately 350 nm; 1014cm−3p-type doping). The thermal conductivity with three levels of porosity, corresponding to different etching conditions, is shown. The thermal conductivity decreases significantly with increasing porosity. The inset images show the top view of the SiNWs, and the scale bars are 200 nm.
