(Color online) X-ray diffraction patterns of ternary CdxZn1−xO (0 ≤ x ≤ 0.139) (0 ≤ x ≤ 1) alloys.
(Color online) (a) Square of Kubelka-Monk scattering F(R) as a function of photon energy for ternary CdxZn1−xO alloys. (b) Valence band XPS of CdxZn1−xO alloys. (c) Electronic bandgaps (open squares) and band bending (closed triangles) as a function of Cd content in CdxZn1−xO samples. (d) A downward band bending due to an electron accumulation at the near surface.
(Color online) (a) XPS spectra fitting with two Voigt components for the Zn 2p 3/2 core line of CdxZn1−xO with x = 0 and 0.075. (b) The movement of surface band positions of CBM (open circles) and VBM (closed squares) with respect to the Fermi level (dash line) at 0.0 eV.
The experimental data for CdxZn1−xO is listed.
