Present paper is a review of results, obtained in the framework of semiclassical approach in nanophysics.
 Semiclassical description, based on Electrostatics and Thomas–Fermi model was applied to calculate dimensions
 of the electronic shell of a fullerene molecule and a carbon nanotube. This simplified approach
 yields surprisingly accurate results in some cases. Semiclassical approach provides rather good description
 of the dimensions of the electronic shell of a fullerene molecule. Two types of dipole oscillations in a
 fullerene molecule were considered and their frequencies were calculated. Similar calculations were performed
 for a carbon nanotube also. These results look rather reasonable. Three types of dipole oscillations in
 carbon nanotube were considered and their frequencies were calculated. Frequencies of the longitudinal collective
 oscillations of delocalized electrons in carbon peapod were calculated as well. Metallic cluster was
 modeled as a spherical ball. It was shown that metallic cluster is stable; its bulk modulus and the frequency
 of the dipole oscillation of the electronic shell relative to the ions were calculated.
