摘要

在紧密结合理论的框架下，我们研究了单链DNA螺旋包裹的单壁碳纳米管(SWNTs)光学性质的调制。我们预测，某些包裹可能会定性地改变单电子吸收光谱的光在SWNT极化。光学选择规则的提升是由于电离DNA主链的库仑势的纳米管对称性破坏。

DNA-Wrapped Carbon Nanotubes as Potential Optoelectronic Materials

In the frame of tight-binding theory, we investigate modulation of the optical properties of single-wall carbon nanotubes (SWNTs) helically wrapped with single-stranded DNA. We predict that certain wraps may qualitatively change the one-electron absorption spectrum for light polarized across the SWNT. Lifting of the optical selection rules is due to nanotube symmetry-breaking in the Coulomb potential of the ionized DNA backbone.
