High-efficiency heat engine requires a large output power at the cost of less input heat
energy as possible. Here we propose a heat engine composed of serially connected two …

The band structure and electric properties of films created from a partially fluorinated
graphene suspension are analyzed in this paper. As may be inferred from the structural …

The shot noise of current through a metallic double quantum dot structure exhibiting
negative differential conductance is studied. We can exactly solve the master equation and …

The shot noise of the current through a single electron transistor, coupled capacitively with
an electronic box, is calculated, using the master equation approach. We show that the …

In this thesis we first review the Markovian quantum master equation approach and its
underlying theoretical arguments and, subsequently, utilize it in order to investigate two …

We systematically study sequential electron tunnelling through parallel double metallic
quantum dot structures, focusing on the role of inter-dot coupling and parameter asymmetry …

The tunneling through a ferromagnet/normal metal/ferromagnet double junction in the
Coulomb blockade regime is studied, assuming that the spin relaxation time of electron in …

The cotunnelling is systematically studied in comparison to sequential tunnelling in
Coulomb blockade metallic double quantum dot structures, using the standard master …
