Abstract
Recently, Konyashin et al. [I. Konyashin, V. Khvostov, V. Babaev, M. Guseva, J. Mayer, A. Sirenko, A new hard allotropic form of carbon:
dream or reality? International Journal of Refractory Metals and Hard Materials (article in press)] have reported electron energy loss spectra
(EELS) of face centered cubic (fcc) carbon films that indicate unique electronic properties of this particular crystal phase of carbon.
Motivated by that, we have investigated the optical properties of carbon in its fcc phase (Fm¯3m) by means of a first princi
