We simultaneously determined the physical structure and optical transition energies of individual single-walled carbon nanotubes by combining electron diffraction with Rayleigh scattering spectroscopy. These results test fundamental features of the excited electronic states of carbon nanotubes. We directly verified the systematic changes in transition energies of semiconducting nanotubes as a function of their chirality and observed predicted energy splittings of optical transitions in metallic nanotubes.
我们通过将电子衍射与瑞利散射光谱相结合，同时测定了单个单壁碳纳米管的物理结构和光学跃迁能量。这些结果检验了碳纳米管激发电子态的基本特征。我们直接验证了半导体纳米管跃迁能量随其手性的系统变化，并观察到了金属纳米管中光学跃迁的预测能量分裂。
