我们使用非正交紧束缚形式对碳和复合单壁纳米管（包括 BN、BC3 和 BC2N 纳米管）的能量、结构和弹性特性进行了比较研究。我们的计算预测，碳纳米管比任何研究的复合纳米管具有更高的杨氏模量，并且与无缺陷石墨烯片的杨氏模量处于同一数量级。我们与现有的实验结果非常吻合。
We present a comparative study of the energetic, structural, and elastic properties of carbon and composite single-wall nanotubes, including BN, BC3, and BC2N nanotubes, using a nonorthogonal tight-binding formalism. Our calculations predict that carbon nanotubes have a higher Young modulus than any of the studied composite nanotubes, and of the same order as that found for defect-free graphene sheets. We obtain good agreement with the available experimental results.
