Abstract

Here, we present novel aspects of infrared photocurrent and plasmonics in graphene, with a focus on understanding the physical mechanisms of plasmon damping and infrared photovoltage creation [Badioli et al. 2014]. Both far-field and near-field microscopy as well as near-field and far-field photocurrent mapping are used to study the nanoscale interactions between infrared light, hot carriers and plasmon excitations. We report record-high optical field confinement while maintaing relatively high plasmon quality factors (>30) [Woessner et al. 2014].
