Quantum Rings in Magnetic Fields and Spin Current Generation
Michele Cini, Stefano Bellucci
We propose three different mechanisms for pumping spin-polarized currents in a ballistic circuit using a time-dependent magnetic field acting on an asymmetrically connected quantum…
A study of random resistor-capacitor-diode networks to assess the electromagnetic properties of carbon nanotube filled polymers
D. S. Bychanok, A. G. Paddubskaya, P. P. Kuzhir +4
We determined the frequency dependent effective permittivity of a large ternary network of randomly positioned resistors, capacitors, and diodes. A linear circuit analysis of such…
Bouncing transient currents and SQUID-like voltage in nano devices at half filling
Michele Cini, Enrico Perfetto, Chiara Ciccarelli +2
Nanorings asymmetrically connected to wires show different kinds of quantum interference phenomena under sudden excitations and in steady current conditions. Here we contrast the t…
Generalized waveguide approach to tight-binding wires: Understanding large vortex currents in quantum rings
Gianluca Stefanucci, Enrico Perfetto, Stefano Bellucci +1
We generalize the quantum waveguide approach to Hückel or tight-binding models relevant to unsaturated $\p$ molecular devices. A Landauer-like formula for the current density throu…
Filtering of spin currents based on ballistic ring
S. Bellucci, P. Onorato
Quantum interference effects in rings provide suitable means for controlling spin at mesoscopic scales. Here we apply such a control mechanism to the spin-dependent transport in a…
Spin separation in a T ballistic nanojunction due to lateral-confinement-induced spin-orbit-coupling
S. Bellucci, F. Carillo, P. Onorato
We propose a new scheme of spin filtering employing ballistic nanostructures in two dimensional electron gases (2DEGs). The proposal is essentially based on the spin-orbit (SO) int…
