Cathodoluminescence studies of C{sub 60} fullerene-based films and nanostructures
- Russian Academy of Sciences, Ioffe Physico-technical Institute (Russian Federation)
The objects of investigation in this work are submicron Cm fullerene-based films and fullerene nanostructures fabricated by electron-beam lithography. The set of techniques for studying the fullerenes is extended due to attraction of the spectral cathodoluminescence (CL) to either of the initial fullerene films or submicron net structures with period of about 0.9 {mu}m, wall height 0.6 {mu}m, and width about 0.4 {mu}m.The maxima of the CL spectra of the initial C{sub 60} films are in good agreement with the energy-band structure of the amorphous fullerene film. In turn, the CL spectrum of the fullerene net structures possesses both peculiarities of the fullerene energy-band structure and it clearly exhibits the oscillations of the spectrum with a period as large as 0.08 eV. Such periodical fullerence net structures possess the properties of an optical resonator on the system 'fullerene net (n = 2.3)-air (n = 1).'.
