Thermal conductivity of carbon nanotube superlattices: Comparative study with defective carbon nanotubes Project supported by the National Natural Science Foundation of China (Grant Nos. 11404278 and 11275163) and the Science Foundation of Hunan Province, China (Grant No. 2016JJ2131). |
(color online) Time dependence of normalized heat current autocorrelation functions (HCACF). (a) Normalized HCACF for pristine CNTs (black line), DCNTs with 50% SW defects (red line), and CNTSLs with 50% SW defects (green line). (b) Long-time region of panel (a). (c) Normalized HCACF for DCNTs with different concentration SW defects. (d) Long-time region of panel (c). The black lines in all figures draw the zero axis for reference. |
