Paper on exciton dynamics in silver nanowires published online

A recently published paper,"Real-Time TDDFT Studies of Exciton Decay and Transfer in Silver Nanowire Arrays," focuses on exciton dynamics, transfer, and decay in silver nanowires. One silver nanowire was initially excited and then coupled to a second nanowire with varying separation distances between them. The electronic density of the total system was then propagated in time with real-time TDDFT. Exciton transfer and diffusion can then be interpreted by observing the oscillating dipole of the total system. This paper focuses on the dephasing mechanism and presents an upper bound for exciton decay time. This work is published in the Journal of Physical Chemistry C.
