利用低阻电接触，我们测量了金属单壁碳纳米管的本征高场输运性质。单个纳米管似乎能够携带密度超过10（9）A/cm（2）的电流。随着偏置电压的增加，电导由于电子的散射而急剧下降。我们表明，电流-电压特性可以解释考虑光学或区界声子发射作为主导的散射机制在高场。
Using low-resistance electrical contacts, we have measured the intrinsic high-field transport properties of metallic single-wall carbon nanotubes. Individual nanotubes appear to be able to carry currents with a density exceeding 10(9) A/cm(2). As the bias voltage is increased, the conductance drops dramatically due to scattering of electrons. We show that the current-voltage characteristics can be explained by considering optical or zone-boundary phonon emission as the dominant scattering mechanism at high field.
