RESONANCE RAMAN EFFECT IN SINGLE WALL CARBON NANOTUBES

实验采用近红外，可见光和紫外激光来绘制 碳纳米管的共振拉曼谱。 目标是提供 理论一维电子行为的实验验证 和单壁纳米管的振动结构预测。 一 一个惊人的结果是，一些人的位置 由于纳米管，相对于激光波长的拉曼带 声子模和电子能量的直径依赖性 间隙，以及由此产生的电子-声子耦合。

The experiments employ NIR, visible, and UV lasers to map the resonance Raman profile of carbon nanotubes. The goal is to provide experimental verification of the theoretical 1-D electronic behavior and the vibrational structure predicted for single wall nanotubes. A striking result is the confirmed dependence of the positions of some Raman bands with respect to the laser wavelength, due to the nanotube diameter dependence of both the phonon modes and the electronic energy gap, and the resultant electron-phonon coupling.
