Figures

Image of FIG. 1.
FIG. 1.

The Squared optical absorption coefficient versus photon energy for the undoped ZnO and Al-doped ZnO films of different thickness (thickness shown as the number behind AZO-). Bandgap values were determined by a linear extrapolation along the leading edge curve to the background.

Image of FIG. 2.
FIG. 2.

VB-XPS of ZnO and the 362 nm thick Al-doped ZnO films are displayed in the region of VB and Zn 3 d. The position (ξ) of the VBM relative to the Fermi level is obtained from the linear extrapolation of the band edge (see the inset).

Image of FIG. 3.
FIG. 3.

A fragment of powder x-ray diffraction spectra for the undoped ZnO and Al-doped ZnO films deposited at 500 °C from 5, 10, 20, and 30 ml of precursor solutions, which resulted in films of different thicknesses.

Tables

Generic image for table
Table I.

Optical and electronic measurements for the undoped ZnO and Al-doped ZnO films. Film thickness is extracted from the UV-Vis transmittance data. Electron density is measured by Hall effect measurements.

Generic image for table
Table II.

Lattice parameters (a and c), grain size, out-plane strain (δ), and in-plane stress (σ) for the undoped ZnO film, Al-doped ZnO films, and ZnO bulk reference. ZnO bulk reference data adapted from database (JCPDF number: 00-003-0888).
