Voltage Waveform Tailoring (VWT), which is based on the simultaneous\u003Cbr \/\u003E\nuse of a set of excitation frequencies, has been demonstrated to provide an efficient\u003Cbr \/\u003E\ncontrol of the Electron Energy Probability Function (EEPF) in such plasmas and,\u003Cbr \/\u003E\nthus, allows optimizing the electron impact driven excitation and dissociation processes\u003Cbr \/\u003E\nas compared to the classical single-frequency operation mode. In this work, the\u003Cbr \/\u003E\neffects of changing the driving frequencies on the spatio-temporally resolved electron\u003Cbr \/\u003E\npower absorption dynamics, the generation of helium metastables and the dissociation\u003Cbr \/\u003E\nof nitrogen molecules are investigated in He\/N2 plasmas based on experiments and\u003Cbr \/\u003E\nsimulations. We find that under a single-frequency excitation, the plasma and helium\u003Cbr \/\u003E\nmetastable densities are enhanced as a function of the driving frequency at a fixed\u003Cbr \/\u003E\nvoltage. When using valleys-type driving voltage waveforms synthesized based on\u003Cbr \/\u003E\nconsecutive harmonics of the fundamental driving frequency, the spatial symmetry of\u003Cbr \/\u003E\nthe electron power absorption dynamics and of the metastable density profile is broken.\u003Cbr \/\u003E\nIncreasing the fundamental frequency at a constant voltage is found to drastically\u003Cbr \/\u003E\nenhance the plasma and metastable densities, which is a consequence of the change\u003Cbr \/\u003E\nof the EEPF. Finally, we compare the energy efficiency of the formation of radicals\u003Cbr \/\u003E\nunder single-frequency and VWT operation at different driving frequencies. For a\u003Cbr \/\u003E\ngiven power dissipated in the plasma, VWT yields a higher helium metastable as well\u003Cbr \/\u003E\nas electron density and a higher dissociation rate of N2.\u003C\/p\u003E\n","url":"https:\/\/rdpcidat.rub.de\/dataset\/effects-driving-frequencies-micro-atmospheric-pressure-hen2-plasma-jets-driven-tailored","state":"Active","log_message":"Update to resource Fig 6.
