“…A loss of 19 wt% of Bi 2 O 3 has been recorded for the process conducted at 1,150 °C for 90 min by emission spectroscopy [20][21][22]. The other reports found that all interlayers in Bi-doped polycrystalline ZnO take on a thin, amorphous and rich nanostructure phase structure after being annealed above eutectic temperature [23].…”

“…Zinc oxide has a wide bandgap of 3.3 eV at room temperature and forms a wurzite structure, which is an n-type semiconductor material with both good electronic and optical properties because of a deviation from the stoichiometry owing to the existence of intrinsic defects such as O vacancies and Zn interstitials [4,5] . Many studies have been conducted on the sintering of several doped ZnO systems, such as Sb-doped ZnO [6,7] , Bi-doped ZnO [8] , Mn-doped ZnO [9] and Al-doped ZnO [10,11] . Among these studies the doping of Al in ZnO showed conductivity enhancement along with improved transparency [12,13] , and the resulting material is regarded as a potential candidate as the substitutes for indium-tin-oxide (ITO) materials [14] .…”

Hexagonal Al-doped zinc oxide (ZnO) powders with a nominal composition of Zn 1−x Al x O (0≤x≤0.028) were synthesized by the co-precipitation method. The contents of the Al element in the samples were measured by the inductively coupled plasma-optical emission spectroscopy (ICP-OES) technique. The structures of the Zn 1−x Al x O (0≤x≤0.028) compounds calcined at 1000 and 1200℃ have been determined using the Rietveld full-profile analysis method. Rietveld refinements of the diffraction data indicated that the addition of Al initially has a considerably positive effect on the decreasing of the lattice parameters a and c of Zn 1−x Al x O, but the effect becomes very slight and even negative with the further increase of the Al content. The solid solubility limit of Al in ZnO (mole fraction y) is 2.2l%, resulting in Zn 0.978 Al 0.22 O. It seems that when the Al content is excessive, Al prefers to form a ZnAl 2 O 4 compound with ZnO, but not to incorporate into the ZnO lattice to occupy the Zn 2+ cites. Two phases, [ZnO] (or Al-doped ZnO) and [ZnAl 2 O 4 ], are obviously segregated in Zn 1−x Al x O while the value of x is larger than 0.024. The UV-Vis absorption spectra show that the Al-doped ZnO exhibits a red-shift in the absorption edge without reduced transmission compared with pure ZnO, which also confirms that Al ions enter the ZnO lattice and form a Zn 1−x Al x O solid solution.Al-doped zinc oxide (ZnO), co-precipitation method, X-ray diffraction, crystal structure

The shape effect of microtwins on high‐resolution transmission electron microscopy (HRTEM) images is demonstrated with the help of a detailed comparison between experimental HRTEM images of recrystallized silicon (including many microtwins) and corresponding dynamical simulations. The analysis points to an important fact: The shape effect of microtwins leads to artificial contrasts. (© 2008 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
