Optical properties and electron transport in low-dimensional nanostructures

Abstract

We present the theory of the electronic transfer and the optical properties of the quasi-zero dimensional quantum nanostructures, like quantum dots or the DNA molecule. The theory is based on the multiple scattering of the charge carriers in the quasi-zero dimensional nanostructures leading to the manifestation of the nonadiabatic influence of the atomic lattice on the charge carriers. The theory is based on the nonequilibrium Green's functions and the quantum kinetic equations. Three examples of the electronic motion in the small systems are presented, together with a comparison of the theoretical results with their experimental counterparts. The comparison with the experiments underlines importance of the electron-phonon interaction in nanostructures.
