X-ray photoelectron spectroscopy study and thermoelectric properties of Al-doped ZnO thin films

Dependence of the properties of sputter deposited Al-doped ZnO thin films on base pressure

“…All atomic spectra were calibrated by using the hydrocarbon C 1 s peak at 284.6 eV as a reference. The Zn 2p 3/2 and Al 2p 3/2 core lines (not shown here) exhibit a highly symmetric shape centered at 1021.79 eV and 74 eV, respectively, which corresponds to Zn O bonds and Al O bonds in AZO [13]. No metallic Zn or Al with binding energies of 1021.5 eV [14] and 72.7 eV [15] was observed.…”

Room temperature deposition of Al-doped ZnO thin films on glass by RF magnetron sputtering under different Ar gas pressure

“…Chemical state changes in the AZO thin films were therefore analyzed by XPS. The Zn 2p 3/2 and Al 2p 3/2 core lines (not shown here) were highly symmetric and centered at 1021.79 ± 0.10 eV and 74 ± 0.10 eV, respectively [23]. No metallic Zn or Al, binding energies 1021.5 eV [24] and 72.7 eV [25], respectively, were observed.…”

Flash synthesis of Al-doping macro-/nanoporous ZnO from self-sustained decomposition of Zn-based complex for superior gas-sensing application to n-butanol

“…From Fig. 6(b), the XPS spectra of Zn2p shows two peaks of Zn2p 3/2 and Zn2p 1/2 , of which the binding energy locates at 1021.9 and 1044.9 eV with the splitting of 2p doublet of 23.0 eV, while metallic Zn with a binding energy of 1021.5 eV [27] can not be observed, indicating that Zn exists in the form of Zn 2+ in oxidized state [15,28]. The core level XPS peak of Al2p locates at 74.2 eV (Fig.…”
