Tunable spin dependent transport in the dor-ring nanostructure
Barbara Kedzierska, Anna Gorczyca-Goraj, Elzbieta Zipper +1
We study spin-dependent transport through a quantum nanostructure composed of a quantum dot (QD) surrounded by a quantum nanoring. The nanostructure is side-attached to source and…
Dot-ring nanostructure: Rigorous analysis of many-electron effects
Andrzej Biborski, Andrzej P. Kądzielawa, Anna Gorczyca-Goraj +3
We discuss the quantum dot-ring nanostructure (DRN) as canonical example of a nanosystem, for which the~interelectronic interactions can be evaluated exactly. The system has been s…
Quantum Dot-Ring Nanostructure - a Comparison of Different Approaches
Iwona Janus-Zygmunt, Barbara Kedzierska, Anna Gorczyca-Goraj +2
It has been recently shown that a nanostructure composed of a quantum dot surrounded by a quantum ring possesses a set of very unique characteristics that make it a good candidate…
Charge transport through a semiconductor quantum dot-ring nanostructure
Marcin Kurpas, Barbara Kędzierska, Iwona Janus-Zygmunt +4
Transport properties of a gated nanostructure depend crucially on the coupling of its states to the states of electrodes. In the case of a single quantum dot the coupling, for a gi…
Electrical control of spin relaxation time in complex quantum nanostructures
M. Kurpas, B. Kędzierska, I. Janus-Zygmunt +2
Spin related phenomena in quantum nanostructures have attracted recently much interest due to fast growing field of spintronics. In particular complex nanostructures are important…
Wave function engineering in quantum dot-ring nanostructures
Elzbieta Zipper, Marcin Kurpas, Maciej M. Maska
Modern nanotechnology allows producing, depending on application, various quantum nanostructures with the desired properties. These properties are strongly influenced by the confin…
