Dielectric function of CuBr${}_{\mathrm{x}}$I${}_{1-\mathrm{x}}$ alloy thin films

Michael Seifert, Evgeny Krüger, Michael S. Bar +6

We study the dielectric function of CuBr${}_{\mathrm{x}}$I${}_{1-\mathrm{x}}$ thin film alloys using spectroscopic ellipsometry in the spectral range between 0.7 eV to 6.4 eV, in combina…
