What is Plasmonics and Its Role in Optoelectronics?
[Plasmonics]() involves the study of plasmons, which are collective oscillations of free electron gas density. Nanostructured materials can support surface plasmons, leading to enhanced electromagnetic fields at the nanoscale. This property is exploited in optoelectronics to develop components like [plasmonic sensors](), which are highly sensitive and can detect minute changes in the environment, and plasmonic photovoltaics, which aim to improve the efficiency of solar cells.
