Unified Description of Inelastic Propensity Rules for Electron Transport through Nanoscale Junctions
Nicolás Lorente, member of the Theory and Simulation group at CIN2 (CSIC-ICN), together with other researchers, published the paper 'Unified Description of Inelastic Propensity Rules for Electron Transport through Nanoscale Junctions' on Phys. Rev. Lett. 100, 226604 (2008).
We present a method to analyze the results of first-principles based calculations of electronic currents including inelastic electron-phonon effects. This method allows us to determine the electronic and vibrational symmetries in play, and hence to obtain the so-called propensity rules for the studied systems. We show that only a few scattering states-namely those belonging to the most transmitting eigenchannels-need to be considered for a complete description of the electron transport. We apply the method on first-principles calculations of four different systems and obtain the propensity rules in each case.
