Scaling of exciton binding energy with external dielectric function in carbon nanotubes
Andrew G. Walsh, A. Nickolas Vamivakas, Yan Yin +4
We develop a scaling relationship between the exciton binding energy and the external dielectric function in carbon nanotubes. We show that the electron-electron and electron-hole…

Phase sensitive detection of dipole radiation in a fiber-based high numerical aperture optical system
A. N. Vamivakas, M. Dogan, S. B. Ippolito +4
We theoretically study the problem of detecting dipole radiation in an optical system of high numerical aperture in which the detector is sensitive to \textit{field amplitude}. In…

Chirality dependence of the radial breathing phonon mode density in single wall carbon nanotubes
A. N. Vamivakas, Y. Yin, A. G. Walsh +3
A mass and spring model is used to calculate the phonon mode dispersion for single wall carbon nanotubes (SWNTs) of arbitrary chirality. The calculated dispersions are used to dete…
