Journal ArticleDOI
Particle agglomeration study in rf silane plasmas: In situ study by polarization-sensitive laser light scattering
C. Courteille,Christoph Hollenstein,J.-L. Dorier,W. Schwarzenbach,Alan Howling,Enric Bertran,G. Viera,Rodrigo Martins,A. Maçarico +8 more
TL;DR: In this article, the authors used a Brownian free molecule coagulation model to determine the time evolution of particle size and their number density in situ multi-angle polarization-sensitive laser light scattering.
Journal ArticleDOI
Sheath impedance effects in very high frequency plasma experiments
TL;DR: In this paper, the frequency dependence of the ion energy distribution at the ground electrode was measured by mass spectrometry in a symmetrical capacitive argon discharge, where the capacitive sheaths are thinner at high frequencies which accentuates the high frequency reduction in sheath impedance.
Journal ArticleDOI
Anionic clusters in dusty hydrocarbon and silane plasmas
TL;DR: In this paper, measurements of anions and cations are reported for hydrocarbon and silane radio frequency capacitive glow discharges. And the general role of anion in particle formation is discussed in the light of these experiments.
Journal ArticleDOI
Reconstruction of the time-averaged sheath potential profile in an argon radiofrequency plasma using the ion energy distribution
TL;DR: In this article, the authors used particle-in-cell (PIC) simulations to reconstruct the profile of the time-averaged potential in the sheath of an argon plasma in a capacitive reactor.
Journal ArticleDOI
Global visualization of powder trapping in capacitive RF plasmas by two-dimensional laser scattering
J.-L. Dorier,Christoph Hollenstein,Alan Howling,C. Courteille,W. Schwarzenbach,A. Merad,Jean-Pierre Boeuf +6 more
TL;DR: In this paper, a cross section of a capacitive discharge is illuminated with an expanded laser beam, and global scattered light is recorded by camera, and a small amount of particles trapped in an argon plasma is visualized using the scattered intensity.
