Emerging Directions in Plasmonics

Plasmonics enables a wealth of applications, including photocatalysis, photoelectrochemistry, photothermal heating, optoelectronic devices, and biological and chemical sensing, while encompassing a broad range of materials including coinage metals, doped semiconductors, metamaterials, 2D materials, and chiral assemblies. Applications in plasmonics benefit from the large local electromagnetic field enhancements generated by plasmon excitation, as well as the products of plasmon decay, including photons, hot charge carriers, and heat. This special topic highlights recent work in both theory and experiment that advances our fundamental understanding of plasmon excitation and decay mechanisms, showcases new applications enabled by plasmon excitation, and highlights emerging classes of materials that support plasmon excitation.
