Molecular spectroscopy at nonequilibrium
Molecular spectroscopy at nonequilibrium
There is a recent surge of interest in probing molecular conduction junctions by optical means sometimes assisted by local electromagnetic field enhancement associated with plasmon excitations. A proper theoretical treatment of such phenomena should take into account the temporal response of both macroscopic contacts and molecule, and combine two new directions in theoretical research – molecular electronics and molecular plasmonics. Like older “standard” spectroscopies, junction optical spectroscopies are expected to play important roles in the field of molecular electronics both as diagnostic methods and as control tools for molecular devices. We develop theoretical tools for treatment of both transport and optical features of non-equilibrium molecular systems.
