“…In this case, l min = 5 and the effective potential has a minimum at ρ min = 2.4 a , in contrast to ρ min = 2.9 a ( l min = 8) for the conducting disk. These results are similar to those for tubular image states91011.…”

“…Similar extended electronic states were predicted to form91011 and observed1213 above the surfaces of metallic carbon nanotubes (CNT). In these tubular image state (TIS), the electron is attracted to its hole image formed on a highly (longitudinally) polarizable CNT surface.…”

“…Because of the highly correlated nature of DESs, the highly excited electron orbiting such discoid structures might be prone to decay (angular momentum exchange with material electrons). This electron-electron damping mechanism was much less significant in TISs, where the electron coupling to nanotube vibrations was the dominant damping mechanism10.…”

We study highly excited diskoid-like electronic states formed in the vicinity of charged and strongly polarizable diskotic nanostructures, such as circular graphene flakes. First, we study the nature of such extended states in a simple two-electron model. The two electrons are attached to a point-like nucleus with a charge 2+, where the material electron is forced to move within a 2D disk area centered at the nucleus, while the extended electron is free to move in 3D. Pronounced and complex correlations are revealed in the diskoid-like states. We also develop semiclassical one-electron models of such diskotic systems and explain how the one-electron and many-electron solutions are related.

“…In addition, bands of TIS can be formed above 1D and 2D periodic arrays of nanotubes 10 . The collapse of these states on the material surface is predicted to be very slow and to be mainly due to the excitation of circularly polarized phonons 11 . TIS are also an interesting and rich platform for investigating quantum chaos in the nanoscale 12 …”

We discuss the use of Tubular Image States (TIS) of electrons in the vicinity of nanotubes as a new vehicle for controlling and optically addressing nanoscale devices. We show that the stability of the TIS arises from the interplay between the attractive image potentials and the repulsive centrifugal potentials arising from the rotation of the electron about the cylindrically shaped nanotubes. We discuss the theory and some of the potential applications of TIS, and, in particular, the trapping of a single electron by a quadrupole made up of four nanotubes in the so‐called “nano‐Paul trap” configuration.
