Breakdown behavior in radio-frequency argon discharges

Path Integral Monte Carlo Simulations of Positronium in Argon

Positrons are a useful and non-destructive tool for probing materials; their current uses range from detecting changes in weapons materials [1] to determining whether a diamond is natural or synthetic [2]. Because the positron is the antiparticle of the electron, there are no positrons present in ordinary matter, and it is possible to closely determine what happens to positrons sent into a mate...

Efficient Monte Carlo Device Modeling

A single-particle approach to full-band Monte Carlo device simulation is presented which allows an efficient computation of drain, substrate and gate currents in deep submicron MOSFETs. In this approach, phase-space elements are visited according to the distribution of real electrons. This scheme is well adapted to a test-function evaluation of the drain current, which emphasizes regions with l...

Spatiotemporal electron dynamics in radio-frequency glow discharges: fluid versus dynamic Monte Carlo simulations

A particle-in cellldynamic Monte Carto simulation technique was developed to study the spatiotemporal electron dynamics in radio-frequency glow discharges. The electric field profile in a parallel plate one-dimensional geometly was obtained from a self-consistent fluid simulation. Using this profile, the particlein-celVdynamic Monte Carto simulation yielded the spatiotemporal electron velocity ...

Physics of high-pressure helium and argon radio-frequency plasmas

The physics of helium and argon rf discharges have been investigated in the pressure range from 50 to 760 Torr. The plasma source consists of metal electrodes that are perforated to allow the gas to flow through them. Current and voltage plots were obtained at different purity levels and it was found that trace impurities do not affect the shape of the curves. The electron temperature was calcu...
