Phys. Rev. Lett. 89, 115504 (2002) [4 pages]Spontaneous Decay of Excited Atomic States near a Carbon Nanotube
The spontaneous decay process of an excited atom placed inside or outside a carbon nanotube is analyzed. Calculations have been performed for various achiral nanotubes. The effect of the nanotube surface is shown to increase the atomic spontaneous decay rate by up to 6 orders of magnitude compared with that of the same atom in vacuum. This increase is associated with nonradiative decay via surface excitations in the nanotube. © 2002 The American Physical Society URL:
