Pseudo-particle approach for charge-transferring molecule-surface collisions
Johannes Marbach, Franz Xaver Bronold, Holger Fehske
Based on a semi-empirical generalized Anderson-Newns model we construct a pseudo-particle description for electron emission due to de-excitation of metastable molecules at surfaces…
Resonant charge transfer at dielectric surfaces
Johannes Marbach, Franz Xaver Bronold, Holger Fehske
We report on the theoretical description of secondary electron emission due to resonant charge transfer occurring during the collision of metastable nitrogen molecules with dielect…
Auger de-excitation of metastable molecules at metallic surfaces
Johannes Marbach, Franz Xaver Bronold, Holger Fehske
We study secondary electron emission from metallic surfaces due to Auger de-excitation of diatomic metastable molecules. Our approach is based on an effective model for the two act…
Plasma walls beyond the perfect absorber approximation for electrons
Franz X. Bronold, Rafael L. Heinisch, Johannes Marbach +1
Plasma walls accumulate electrons more efficiently than ions leading to wall potentials which are negative with respect to the plasma potential. Theoretically, walls are usually tr…
