  We investigate the problem of the electron interacting with the charge
induced on the metal or dielectric surface. We show that the interaction
between the electron and the induced surface charge leads to the lateral
confinement of the electron. As a result the electron propagates parallel to
the surface not as a plane wave but as a wave packet of a Gaussian shape. The
electron moving together with the induced charge can be treated as a new
quasi-particle, which we call inducton. We discuss a possible experimental
evidence for inductons in semiconductor nanostructures, metal-vacuum, and
dielectric-vacuum interfaces.
