Determining plasmonic hot-carrier energy distributions via single-molecule transport measurements
Abstract
Hot carriers are expected to arise in plasmonic nanostructures because of the nonradiative decay of surface plasmons. However, identifying and determining just how “hot” these carriers actually are has been challenging. Reddy et al. devised a technique that looks at the carrier transport through a single molecular junction, which effectively acts as an energy filter, and show that it can be used to determine the distribution of hot carriers in a plasmonic nanostructure (see the Perspective by Martín-Moreno). These hot carriers could be harnessed to enhance the performance of technologies, including plasmon-driven photochemistry, solar energy–harvesting devices, and efficient photodetectors.
