Plasmonic

Part of speech: adjective

Pronunciation: /plæzˈmɒnɪk/

Definitions

1. A branch of physics that deals with the interactions between electromagnetic fields and free electrons in metal or semiconductor nanostructures is termed this
2. This field explores the manipulation of light at the nanoscale through the collective oscillations of electrons in materials
3. A scientific discipline that investigates how light interacts with electrons in metallic or semiconductor nanostructures is referred to as this

Etymology: Plasmonic is a modern scientific coinage, built in English from "plasmon" plus the suffix "-ic." The source chain runs back to Ancient Greek "plássein," meaning "to shape or mould," which gave "plásma," a thing moulded or formed. Latin borrowed this as "plasma," and English later adopted it, so the root's original idea is simply something shaped. The "-on" in "plasmon" is the more recent part. It follows the pattern of physics terms ending in "-on," such as "electron" and "ion," and "plasmon" names a quantum of collective electron oscillation in a material, the same kind of collective motion that the word "plasmonic" describes. Here "electron" itself was formed from Greek "ḗlektron," meaning amber, which hints at how far scientific vocabulary can travel from its roots. The suffix "-ic" comes through Latin "-icus," passing into English largely through Old French and Middle English. Adding it to "plasmon" produced an adjective for anything relating to plasmons, which is why the word describes devices and materials that manipulate light through electron oscillation rather than the substance "plasma."

Synonyms: plasmatic, light-matter interaction, optical, nanoplasmonic, electromagnetic
