Reports Summarize Physics Condensed Matter Findings from University of Puerto Rico (The effect of dephasing on the thermoelectric efficiency of molecular junctions)

By a News Reporter-Staff News Editor at Physics Week -- Current study results on Physics Condensed Matter have been published. According to news reporting originating in Humacao, Puerto Rico, by VerticalNews editors, the research stated, "In this work we report the results of theoretical analysis of the effect of the thermal environment on the thermoelectric efficiency of molecular junctions. The environment is represented by two thermal phonon baths associated with the electrodes, which are kept at different temperatures."

The news reporters obtained a quote from the research from the University of Puerto Rico, "The analysis is carried out using the Buttiker model within the scattering matrix formalism to compute electron transmission through the system. This approach is further developed so that the dephasing parameters are expressed in terms of relevant energies, including the thermal energy, strengths of coupling between the molecular bridge and the electrodes and characteristic energies of electron-phonon interactions."

According to the news reporters, the research concluded: "It is shown that the latter significantly affect thermoelectric efficiency by destroying the coherency of electron transport through the considered system."
