Une source de lumiere de dimension atomique est realisee a l’aide d’un microscope a effet tunnel (STM). Cette source de photons est localisee a la jonction entre une pointe, que l’on peut deplacer avec une precision atomique, et un echantillon

International audience; We study the scattering of electrically excited surface plasmon polaritons (SPP) from individual nanostructures. The tunneling electrons from a scanning tunneling microscope (STM) are used to excite an outgoing , circular SPP

Publikováno v: Journal of Physics: Condensed Matter. 18:S1927-S1934

Powering and controlling the operation of a single molecule adsorbed on a surface can be achieved by using the tip of a scanning tunnelling microscope (STM) as an atomic-size source of electrons. We review the various electronic excitation processes

Atomic-scale studies of hydrogenated semiconductor surfaces

Publikováno v: Progress in Surface Science. 81:1-51

The adsorption of hydrogen on semiconductors strongly modifies the electronic and chemical properties of the surfaces, whether on the surface or in the sub-surface region. This has been the starting point, in recent years, of many new areas of resear

Electronic processes producing O+ ion photodesorption from oxygen adsorbed on Si(111)7×7

Autor: Geneviève Comtet, Gérald Dujardin

Publikováno v: Surface Science. 593:256-263

The resonant core photon excitation of adsorbates on surfaces is expected to produce well-controlled electronic processes leading to selective photodesorbed products. Here, we have investigated O + ion photodesorption from oxygen adsorbed on Si(1 1 1
