  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.
