title = "Optical properties of nanocrystalline FeSi 2 and the effects of hydrogenation",
abstract = "Various optical measurements confirm that optical absorption in uniform thin films made from nanocrystalline iron disilicide (nc- Fe Si2) with a 3-5 nm radius is larger by about 10% than that of single crystalline Β-Fe Si2. It is also found that the hydrogenation of nc- Fe Si2 changes strongly its optical characteristic energies. The nanocrystalline state appears characteristically in the imaginary part of dielectric constants of Β-Fe Si2 around 2-3 eV.",
