Figure 3From: Effects of Sn doping on the morphology and properties of Fe-doped In2O3 epitaxial filmsOptical properties of the (Sn, Fe)-codoped films. (a) Transmittance spectra of x% Sn- and 5% Fe-doped In2O3 films. (b) Corresponding plot of (αhν)2 versus hν. The intercept of linear extrapolation gives the optical band gap.Back to article page
