Влияние импульсного ионного пучка на электронную структуру атомов азота в многостенных углеродных нанотрубках, легированных азотом

The changes of the chemical state of nitrogen atoms in the structure of nitrogen-doped multiwalled carbon nanotubes (N-MWCNTs) after impact of pulsed ion beam at various parameters of the beam (energy density, number of pulses) have been investigated with the use of X-ray photoelectron spectroscopy (XPS). It has been established that irradiation leads to a reduction of the total amount of nitrogen in N-MWCNTs. The single pulse irradiation of ion beam at the energy densities of 0,5; 1; 1,5 J/cm2 leads to restructuring of the nitrogen from pyridinic and pyrrolic configuration to graphitic state.
