In this letter, we investigated the temperature dependence of the in-plane (E12g) and out-of-plane (A1g) Raman modes of multi-walled MoS2 nanotubes fabricated from anodic aluminum oxide (AAO) templates. The frequencies of these two phonon modes were found to vary linearly with temperature. In this linear region, the first-order temperature coefficients for the A1g and E12g modes equaled –(1.15 ± 0.06)×10−2 cm−1/K and –(1.11 ± 0.1)×10−2 cm−1/K, respectively. The thermal conductivity of the multi-walled MoS2 nanotubes at room temperature was estimated to be in the range of 4.8 ± 0.1 to 11.1 ± 0.2 W m−1 K−1.

多壁二硫化钼纳米管的温度相关拉曼光谱和热导率

在这封信中，我们研究了由阳极氧化铝 (AAO) 模板制成的多壁 MoS2 纳米管的面内 (E12g) 和面外 (A1g) 拉曼模式的温度依赖性。发现这两种声子模式的频率随温度线性变化。在这个线性区域，A1g 和 E12g 模式的一阶温度系数等于 –(1.15 ± 0.06)×10−2 cm−1/K 和 –(1.11 ± 0.1)×10−2 cm−1/K，分别。多壁二硫化钼纳米管在室温下的热导率估计在 4.8 ± 0.1 至 11.1 ± 0.2 W m-1 K-1 的范围内。
