Confining Potential

The dissipative quantum dynamics of electron transport in a two dimensional quantum wire is studied. The wire is modeled by a parabolic confining potential in one of the spatial directions. Quantum dissipation is provided by the electron coupling to a phonon bath using a simplified Fröhlich type model, and the problem is solved in closed form. We find that the lateral electron sub-bands give rise to a quasi-periodic behavior of a quantity which is essentially the transport impedance, and this leads to very different behavior of the electron drift velocity as compared to the case without lateral confinement.

Level Change

We studied the coherent electron transport through metal–protein–metal junctions based on a blue copper azurin, in which the copper ion was replaced by three different metal ions (Co, Ni and Zn). Our results show that neither the protein structure nor the transmission at the Fermi level change significantly upon metal replacement. The discrepancy with previous experimental observations suggests that the transport mechanism taking place in these types of junctions is probably not fully coherent.
