Title: | Excitation of Electronic States of N<inf>2</inf> in Radio-Frequency Electric Field by Electron Impact | Authors: | Ristić, Miroslav M. Aoneas, Muna M. Vojnović, Mirjana M. Poparić, Goran |
Keywords: | Electronic states;Nitrogen molecule;Radio-frequency field;Rate coefficients | Issue Date: | 1-Sep-2017 | Journal: | Plasma Chemistry and Plasma Processing | Abstract: | Excitation of electronic states of the N2 molecule by electron impact is recognized as an essential process in nitrogen plasmas that strongly impacts their chemical reactivity and other properties. Many surface and coating technologies are based on radio-frequency plasma discharges in nitrogen. In this paper the electron impact excitation rate coefficients for singlet and triplet electronic states of the N2 molecule have been calculated in non-equilibrium conditions in the presence of a radio-frequency electric field. A Monte Carlo simulation has been performed in order to determine non-equilibrium electron energy distribution functions within one period of the electric field. By using these distribution functions, the excitation rate coefficients have been obtained in the frequency range from 13.56 up to 500 MHz, at reduced electric field values from 200 to 700 Td. |
