Emission and sputtering characteristics of Ne-Ar mixed gas glow discharge plasmas.
The emission characteristics of several Cu lines emitted from a Ne-Ar mixed gas glow discharge plasma were investigated. The addition of small amounts of Ar to a Ne plasma increases the sputtering rate of a Cu sample because Ar ions, which work as the impinging ions for cathode sputtering, are predominantly produced through Penning ionization collisions between Ne metastables and Ar atoms. Ar a...
متن کاملCharacterization of argon direct-current glow discharge with a longitudinal electric field applied at ambient air
A direct-current-driven plasma jet is developed by applying a longitudinal electric field on the flowing argon at ambient air. This plasma shows a torch shape with its cross-section increased from the anode to the cathode. Comparison with its counterparts indicates that the gas flow plays a key role in variation of the plasma structure and contributes much to enlarging the plasma volume. It is ...
متن کاملEmission spectroscopic study on gas-gas interactions in glow discharge plasmas using several binary gas mixtures.
Emission spectra of constituent gas species from glow discharge plasmas using argon-helium, krypton-helium, argon-krypton, and krypton-argon gas mixtures were analyzed to elucidate collisional energy transfer between these gas species occurring in the plasma. In the argon-helium mixed gas plasma, the enhancement or quenching of particular Ar II lines was observed when helium was added to an arg...
متن کاملRf glow discharge optical emission spectrometry for the analysis of arrays of Ni nanowires in nanoporous alumina and titania membranes
During the last decade, a great variety of nanostructures (nanotubes, nanofibers or nanowires) based on metals, carbons, polymers or semiconductors, have been synthesized following different synthesis procedures by using nanoporous anodic alumina membranes (AAM) as templates [1]. The principal reason for using templates of nanoporous AAM as precursor patterns lies on the possibility to obtain, ...
متن کاملAbsolute Spatially- and Temporally-Resolved Optical Emission Measurements of rf Glow Discharges in Argon
Spatially- and temporally-resolved measurements of optical emission intensities are presented from rf discharges in argon over a wide range of pressures (6.7 to 133 Pa) and applied rf voltages (75 to 200 V). Results of measurements of emission intensities are presented for both an atomic transition (Ar I, 750.4 nm) and an ionic transition (Ar II, 434.8 nm). The absolute scale of these optical e...
