Shkop A. Effects of electron-electron and electron-vibron interaction in charge and spin transport in tunnel nanostructures

The thesis is devoted to theoretical study of electron transport in carbon nanotubes and molecular transistors in presence of electron-electron and electron-vibron interaction. It has been shown that for the system of contacts with Majorana nanowire, strongly asymmetric in tunnel couplings, the zero-bias peak of conductance appears. It has been found that in metallic single-wall carbon nanotube the electron-electron interaction induces a gap in charge carriers’ spectrum and causes the chiral tunneling. It has been determined that in the current-voltage characteristics of spintronic molecular transistor the number of current steps is doubled and the regions without steps appear for strong Coulomb interaction. It has been revealed that thermo-induced magnetic shuttling in spintronic molecular transistor is a threshold phenomenon.
