Nanographite Films: Structure and Properties

Nanographite film structures of different morphology have been grown on various substrates using the activated carbon fibers (ACF) as a source of nanographites. As was revealed from the data of Raman spectroscopy, the fabricated films consisted mainly of the same structural blocks as the initial ACF. Scanning electron microscopy was used to study the films morphology. The presence of lengthy zigzag edges in nanographites, which is prerequisite for their nontrivial electronic structure and magnetic characteristics, has been established. The X-ray photoelectron spectroscopy data show the appearance of expressed maxima in the C1s spectra of the films in the usually observable "diffuse" structure of π→π* shake-up satellites, π and π + σ plasmons.
