Abstract:

This study presents the calculation and analysis of electron transport coefficients in gas mixturescomposed of argon (Ar), molecular fluorine (F2), and nitrogen (N2), with a focus on their relevance to gasdischarge applications. Using the BOLSIG+ Boltzmann solver and well-established electron collisioncross-section data, key parameters such as mobility, diffusion coefficients, and ionization coefficients wereevaluated across a range of reduced electric fields (E/N) and mixture ratios. These data serve as criticalinput for the modeling and optimization of low-temperature plasma discharges, particularly in applicationssuch as reactive ion etching and thin film deposition using inductively coupled plasma systems.
