New combined PIC-MCC approach for fast simulation of a radio frequency discharge at low gas pressure. Abstract A new combined PIC-MCC approach is developed for accurate and fast simulation of a radio frequency discharge at low gas pressure and high density of plasma. Test calculations of α − γ transition in a ccrf discharge in helium and argon show a good agreement with experimental data. We de...
متن کامل3D PIC-MCC simulations of discharge inception around a sharp anode in nitrogen/oxygen mixtures
We investigate how photoionization, electron avalanches and space charge affect the inception of nanosecond pulsed discharges. Simulations are performed with a 3D PIC-MCC (particlein-cell, Monte Carlo collision) model with adaptive mesh refinement for the field solver. This model, whose source code is available online, is described in the first part of the paper. Then we present simulation resu...
متن کامل2D PIC Simulation of the DC Discharge in Cylindrical Magnetron
PIC method of plasma simulation is widely used in plasma physics research because of its ability to solve wide range of problems in kinetic approach. Regarding to description of PIC method we refer to [Birdsall et al., 1995]. This work is focused on PIC simulations of dc discharge in cylindrical magnetron device. Magnetrons are used in industry e.g. for thin film layer coating and etching. Many...
متن کاملPIC-MCC Simulations of Capacitive RF Discharges for Plasma Etching
A numerical study of parallel-plate rf discharges in Ar has been performed including the transport of ions and electrons in the sheath on the substrate. We employ a two-dimensional particle-in-cell with Monte Carlo collisions (PIC/MCC) method for an asymmetric capacitive discharge with an external electrical circuit containing a blocking capacitor and an rf power supply. The model gives self-co...
متن کاملPaschen breakdown curve by one-dimensional PIC-MCC simulation
The voltage at which a gas confined in a gap ignites, i.e. the breakdown voltage, is a function of the total pressure (p) and the gap size (d). The understanding of gas discharge has been important in applications of weakly ionized plasmas and studying the properties of the plasma medium, such as nanotechnoogy, ion sources and thrusters [1-2]. We obtained the Paschen breakdown curve by consider...
