General information
Quasi-two-dimensional nanostructures are invaluable for exploring fundamental quantum phenomena which have a number of potential applications in the fields of sensing, lasing, photovoltaic, spin devices, etc. Broken time-reversal symmetry and quantum phase interference in such structures subjected to a transverse magnetic field opens up great perspectives for applications in quantum optics and quantum computing devices. The main goal of this project is to study the background physics and predict controlling mechanisms for magneto-optical, chargeand spin-transport, as well as dynamical response properties of quasi-two-dimensional arrays of semiconductor quantum dots and quantum rings. In our study we will use theoretical and computational methods, such as Exact Diagonalization of the system Hamiltonian, Hartree-Fock Approximation, Density Functional Theories and Liouville-von Neumann equation for density matrix. Extensive “COMSOL Multiphysics” simulations will be used to model active elements based on considered systems and to study their photovoltaic, magneto-optical and other characteristics. Using the results of our study we will try to model future nanodevices based on the quasi-two-dimensional semiconductor heteronanostructures.
