Electrostatic multipoles created by electron localized in narrow-band cylindrical nanolayer

The problem of definition and control of electrostatic field, created by electron, localized in cylindrical nanolayer from InSb is considered. The average values of quadrupole and dipole moments have been calculated and the appropriate corrections in the potential and the electric field strength have been found. The obtained results can be applied in singleelectron transistors, where role of the active functional element will play an InSb cylindrical quantum layer.
