在2 - 300 K温度范围内和20 Hz-1 MHz频率范围内研究了由碳纳米管和二硫化钨纳米管（和富勒烯样纳米颗粒）组成的混合膜的DC和AC电性能。电阻R（T）的温度依赖性在中温范围内表现出波动诱导隧穿模型的典型行为。阻抗的真实的和虚部对频率（Z '（f）和Z”（f））的依赖性分析表明，混合膜（由碳纳米管和无机二硫化钨纳米管组成）内碳纳米管之间的接触势垒的作用随着温度的升高而增加。的活性成分的阻抗被发现占主导地位的混合膜的AC电性能，包括多壁碳纳米管和WS 2纳米粒子在整个可用的温度范围内。
DC and AC electrical properties of hybrid films, consisting of carbon nanotubes and tungsten disulfide nanotubes (and fullerene like nanoparticles) were studied within the 2 ‐ 300 K temperature range and over the 20 Hz ‐ 1 MHz frequency range. The temperature dependences of the resistance R(T) exhibit behavior typical for the fluctuation-induced tunneling model in the intermediate temperature range. Analysis of the dependences of real and imaginary components of the impedance on the frequency (Z’(f) and Z”(f)) demonstrates the rising role of the contact barriers between carbon nanotubes inside hybrid films, consisting of the carbon nanotubes and inorganic tungsten disulfide nanotubes as the temperature was decreased. The active component of the impedance was found to prevail in the AC electrical properties of the hybrid films, consisting of multi-wall carbon nanotubes and WS2 nanoparticles over the entire available temperature range.
