abstract = {A dielectric model comprising band gap transitions and free
electron excitations (Drude model) is successfully applied
to simulate transmittance spectra of ZnO films doped with
$0.5\%,$ $1\%$ and $2\%$ Al. The Drude formula contains a
frequency-dependent damping term in order to get a good fit
in the visible spectral region. Useful physical parameters
obtained from the fit are electron density and mobility
within the grains, film thickness, band gap and refractive
index. The optically determined film thickness agrees with
that obtained with the stylus method within $2\%.$ The
optically determined electronic parameters are compared with
those obtained by electrical measurements. Contrary to thin
In2O3:Sn films, the Drude mobility inside the grains is
similar to the direct current Hall mobility indicating more
perfect film growth without forming pronounced grain
boundaries. Maximum value is 35 cm(2)/V s. The effective
electron mass is estimated to be about 0.6 of the free
electron mass. The refractive index at 550 run decreases
with increasing electron density. (c) 2005 Elsevier B.V. All
