23 February 2007 F. JAVIER GARCÍA DE ABAJO \'Plasmon resonances in metallic nanoparticles\'

Javier García de Abajo

Seminar, February 23rd, 11:30. Seminar Room Collective conduction-electron response in metals produce oscillatory behavior similar to excitations in plasmas. The resulting plasmon modes constitute the basic ingredients of the rapidly growing field of plasmonics, which benefits from recent advances in nanofabrication and nanoparticle synthesis that have led to exciting applications in biosensing and information technologies. A brief summary of plasmons in nanoparticles both isolated and in arrays will be offered in this talk, illustrated by examples of plasmon modes in several particle geometries, ranging from spheres todecahedra, and investigated by theoretical, optical, and valence-excitation electron microscopy techniques (e.g., EELS and cathodoluminescence).

Seminar, 23rd of February, 11:30 h. Conference Room.
Hosted by Prof. Romain Quidant (Plasmon nano-optics)
