Quantum Transport in a Biphenyl Molecule: Effects of Magnetic Flux
نویسنده
چکیده
Electron transport properties of a biphenyl molecule are studied based on the Green’s function formalism. The molecule is sandwiched between two metallic electrodes, where each benzene ring is threaded by a magnetic flux φ. The results are focused on the effects of the molecule to electrode coupling strength and the magnetic flux φ. Our numerical study shows that, for a fixed molecular coupling, the current amplitude across the bridge can be regulated significantly just by tuning the flux φ. This aspect may be utilized in designing nano-scale electronic circuits. PACS No.: 73.23.-b; 73.63.Rt; 73.40.Jn; 81.07.Nb

In recent years, semiconductor nanostructures have become the model systems of choice for investigation of electrical conduction on short length scales. Quantum transport is studied in a two dimensional electron gas because of the combination of a large Fermi wavelength and large mean free path. In the present work, a numerical method is implemented in order to contribute to the understanding ...
متن کاملAharonov-Bohm effects in transport through a square quantum dot molecule
We study the Aharonov-Bohm (AB) effect in a coupled 2×2 quantum dot array with two-terminals. A striking conductance dip arising from the Fano interference is found as the energy levels of the intermediate dots are mismatched. It is lifted in the presence of a magnetic flux. Meanwhile, a novel five peak structure is observed in the conductance for large mismatch. The AB evolution of the linear ...
متن کاملMagnetoresistance of nanoscale molecular devices based on Aharonov-Bohm interferometry.
Control of conductance in molecular junctions is of key importance in the growing field of molecular electronics. The current in these junctions is often controlled by an electric gate designed to shift conductance peaks into the low bias regime. Magnetic fields, on the other hand, have rarely been used due to the small magnetic flux captured by molecular conductors (an exception is the Kondo e...

The magnetoresistance of a one-dimensional electron gas in a metallic ferromagnetic nanowire containing two atomic-size domain walls has been investigated in the presence of spin-orbit interaction. The magnetoresistance is calculated in the ballistic regime, within the Landauer-Büttiker formalism. It has been demonstrated that the conductance of a magnetic nanowire with double domain walls...
