Objective
The Project aims at the elaboration of a general approach to the description of electromagnetic processes in different nanostructures, theoretical investigation of their electromagnetic properties, and development of a physical basis for utilization of these properties in novel nanodevices. Solid-state nanostructures are constitutive and geometric inhomogeneities in semiconductor and dielectric media. Owing to their extremely small dimensions in one or more directions, the spatial confinement of charge carriers is fully developed, thereby providing a discrete spectrum of energy states. In addition, the intrinsic spatial inhomogeneity of nanostructures dictates nanoscale inhomogeneity of electromagnetic fields. Therefore, a consistent theory of electromagnetic processes in nanostructures must take into account the complementary characters of these two key factors whose interplay drastically modifies the electronic and optical properties of nanostructures. Whereas the first factor lies in the focus of current research activity, the role of the second factor was underestimated before. The Project aims to fill this gap for such nanostructures as carbon nanotubes (CNTs) and quantum dots (QDs), since they are very promising for applications. Thus, as a whole, the Project contributes to the elaboration of a novel interdisciplinary research branch the nanoelectromagnetics that is a synthesis of the macroscopic electrodynamics of nonhomogeneous media and the microscopic theory of electronic properties of nanostructures. The concept of an optical nano-antenna, based on finite-length quasi-one-dimensional nanoscale structures, will be developed and justified. Methods of the traditional theory of microwave antenna vibrators will be modified to the optical frequency range and incorporate key properties of nanoscale objects. The features of the problem originate from the interplay of the charge carriers confinement and the light confinement manifesting themselves fully at the nanoscale. A theory and corresponding numerical procedure will be developed and applied for modelling of the plane wave scattering from a finite-length CNT. During the Project, CNTs will be theoretically examined as candidates for novel emitters of terahertz electromagnetic waves. Different physical mechanisms of the generation will be studied theoretically from the viewpoint of realisation of them in novel nanodevices. The Project investigates also quantum-electrodynamical effects in QDs. Under the effect of local fields, we expect the formation of new exciton-photon coupled states, different from ordinary polaritons, and manifestation of a new mechanism of Bose-Einstein condensation in QDs.
