Roll-to-roll radio frequency plasma enhanced chemical vapor deposition (R2R RFCVD) is a technique for large-scale synthesis of high quality graphitic nanopetals. Graphitic nanopetals are petal-like graphene structures with remarkable electrical and mechanical properties with major industrial applications such as microsupercapacitors. RFCVD uses a non-equilibrium plasma with high energy electron...

Kinetic simulation of plasmas in which equilibrium occurs over ion timescales poses a computational challenge due to the disparate timescales of the electron plasma frequency ( 10), the ion plasma frequency ( 10), ion transit frequency ( 10), and the ionization frequency ( 10). To investigate long time scale, low frequency phenomenon a hybrid electrostatic PIC algorithm is presented in which th...

For the self-consistent description of various plasma sources operated in low-pressure (nonlocal, kinetic) regime, Particle-In-Cell simulation approach, combined with Monte Carlo treatment collision processes (PIC/MCC), has become an important tool during past decades. PIC/MCC codes have been developed and maintained by many research groups, some these are available to community as freeware res...

The breakdown phase in a Plasma Focus (PF) device is not yet a well-understood phenomenon, even if widely known to be of great importance in the subsequent evolution of the discharge. A Particle-In-Cell (PIC) method coupled with a Monte-Carlo-Collision (MCC) module has been developed to study the time evolution of electron density and Electron Energy Distribution Function (EEDF) up to few tens ...

Abstract In the past three decades, first principles-based fully kinetic particle-in-cell Monte Carlo collision (PIC/MCC) simulations have been proven to be an important tool for understanding of physics low pressure capacitive discharges. However, there is a long-standing issue that plasma density determined by PIC/MCC shows quantitative deviations from experimental measurements, even in argon...

Abstract The present study investigates the physics of a nanosecond-pulsed microplasma operated at pressure 200 mbar with help Particle-in-Cell simulation Monte Carlo treatment collision (PIC/MCC) and (semi-)analytical models. discharge is ignited in 1 mm gap between two parallel molybdenum electrodes by applying voltage kV-range for several tens to hundreds nanoseconds. A PIC/MCC developed ord...

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...

Abstract A nanosecond Atmospheric Pressure Plasma Jet (ns-APPJ) operated in pure nitrogen is studied by spatially and temporally resolved Optical Emission Spectroscopy (OES) complementing the companion paper Kuhfeld et al. PSST 2023 XXXX , where discharge investigated means of Particle-in-Cell/Monte Carlo Collisions (PIC/MCC) simulations fluid models. Two temporal phases evolution are identifie...
