Plasmón - Wikipedia, La Enciclopedia Libre
En física, un plasmón es un cuanto de oscilación del plasma.El plasmón es la cuasipartícula resultado de la cuantización de las oscilaciones del plasma, de la misma forma que un fotón o un fonón son cuantizaciones de ondas electromagnéticas y mecánicas.Por tanto, los plasmones son oscilaciones de la densidad del gas de Fermi (gas de electrones libres), usualmente a frecuencias ópticas. ...
