1. Quantum and Ballistic Nanodevices
Abstract : In this thesis, electron transport in quantum and ballistic devices was studied. The devices studied here were quantum wires, planar quantum dots, ballistic rectifiers, artificial functional materials, and three-terminal ballistic junctions. The possible application of such devices in the future nanoelectronics was also investigated. READ MORE

2. Modelling of Quantum Transport in Nanostructures
Abstract : In this thesis, theoretical studies of the transport properties of three nanoscale systems: one-dimensional (1D) quantum wires (QWRs), zero-dimensional (0D), laterally confined, double-barrier resonant tunnelling structures (DBRTSs) and three-terminal ballistic junctions (TBJs), have been performed. In the first part of the thesis, an overview of the realization and properties of such systems is given along with a description of modelling tools used in the calculations. READ MORE

4. Nonequilibrium Effects in Mesoscopic Josephson Junctions
Abstract : In this thesis we present a unified scattering approach to current transport in mesoscopic Josephson junctions out of equilibrium. A nonequilibrium situation is created by either quasiparticle injection into the normal part of the junction, or by applying a dc-voltage between the two superconducting electrodes. READ MORE
