Abstract
U okviru ovog rada proučavat ćemo tunelirajući električni i termalni transport između spinski polariziranih elektroda medu kojima se nalazi tanki film s distribucijom kvantnih točaka. Jednoelektronska stanja u kvantnoj točki spinski su diskriminirana te se njima odvija odgovarajući spinski polarizirani transport tuneliranjem elektrona medu elektrodama pod utjecajem narinutog prednapona i/ili razlike temperatura. Problem transporta bit će formuliran u formalizmu tzv. ”master equation” iz koje će biti izvedene kinetičke jednadžbe za populaciju kvantne točke elektronom ovisno o učestalostima tuneliranja određenim zadanim parametrima sustava.
Abstract (english)
In this thesis we study electronic and thermal transport between two metallic leads (one is spin-polarized) through a thin layer of quantum dots in an external magnetic field. Spin-polarized transport of electrons occurs via sequential tunnelling through spin-discriminated quantum dots with the control of bias voltage and/or temperature difference between the leads. We model the problem in the formalism of ”master equation”, from which we derive kinetic equations for the dynamic population of the quantum dot with the electron. With the stationary solution, we obtain the current in the system, from which we analyse electronic and thermal transport, depending on the bias voltage and temperatures of the leads. We find the conditions under which we have spin-polarized and thermal transport, as well as the conditions under which we have transfer of energy from the colder to the hotter lead, that is, further cooling of the colder lead.
