Plasma generation by inductive coupling with a planar resonant RF network antenna

Christoph Hollenstein, Alan Howling, Philippe Frédérique Bruno Guittienne, Sylvain Lecoultre

A planar antenna operating at 13.56MHz is presented for potential applications in plasma processing. It consists of interconnected elementary resonant meshes composed of inductive and capacitive elements. Due to its structure, the antenna exhibits a set of ...

Resonant planar antenna as an inductive plasma source

Christoph Hollenstein, Alan Howling, Philippe Frédérique Bruno Guittienne, Sylvain Lecoultre

A resonant planar antenna as an inductive plasma source operating at 13.56 MHz inside a low pressure vacuum vessel is presented for potential plasma processing applications. Its principle consists in interconnecting elementary resonant meshes composed of i ...

UV-visible absorption of small gold clusters in neon: Au-n (n=1-5 and 7-9)

Wolfgang Harbich, Alexandre Rydlo, Sylvain Lecoultre

We present optical absorption spectra in the UV-visible range (1.5 eV < E < 6 eV) for mass selected neutral gold clusters Au-n (n = 1-5 and 7-9) embedded in solid Ne at 7 K. The experimental spectra are compared with time-dependent density functional calcu ...

Optical absorption of small copper clusters in neon: Cu-n, (n=1-9)

Wolfgang Harbich, Sylvain Lecoultre, Alexandre Rydlo

We present optical absorption spectra in the UV-visible range (1.6 eV < omega < 5.5 eV) of mass selected neutral copper clusters Cu-n(n = 1-9) embedded in a solid neon matrix at 7 K. The atom and the dimer have already been measured in neon ma ...

Ultraviolet-visible absorption of small silver clusters in neon: Ag-n (n=1-9)

Wolfgang Harbich, Sylvain Lecoultre, Alexandre Rydlo

We present optical absorption and fluorescence spectra in the UV-visible range of size selected neutral Ag-n clusters (n = 1-9) in solid neon. Rich and detailed optical spectra are found with linewidths as small as 50 meV. These spectra are compared to tim ...

Propriétés optiques de petits agrégats de métaux nobles en matrice de néon

Sylvain Lecoultre

The optical properties of small noble metal clusters have been studied by absorption and fluorescence for sizes between 1 and 10 atoms. The experimental technique consists in depositing size-selected clusters in a neon matrix and analyzing with a spectrome ...

Gold dimer in neon: an absorption and fluorescence study

Wolfgang Harbich, Sylvain Lecoultre, Alexandre Rydlo

We report for the first time the absorption and fluorescence spectra of gold dimers in a neon matrix. The dimer absorption spectra show the A←X transition predicted from measurements in the gas phase and not observed so far in a matrix, as well as the so-c ...

Optical absorption of small silver clusters: Agn, (n=4–22)

Sylvain Lecoultre, Alexandre Rydlo, Fabien Conus

We present a joint theoretical and experimental investigation of the absorption spectra of silver clusters Agn (4
