“…However, it is difficult to achieve reliable and reproducible p-type ZnO for developing ZnO-based devices because ZnO exhibits natural n-type conductivity. There have been a number of recent reports on the synthesis of p-type ZnO doped by group-V elements (e.g., N, P, and As) substituting for O, or group-I elements (e.g., Li and Na) substituting for Zn, to realize high-quality p-type ZnO [7][8][9][10]. Among these dopants, N is a shallow acceptor and its ionic radius is very similar to that of O, unlike those of P and As.…”

“…They have larger atomic radii in their periods which causes weak metallic bonding and therefore low ionization energy. On the other hand oxidation of the samples can be done effortlessly [7,8].…”

In this study, we report an application of facile and low-cost successive ionic layer adsorption and reaction method to investigate nanostructured CdO films. We have tried to enhance some physical properties of nanostructured CdO films by group-I (K, Li and Na) elements doping. The crystal structures, morphology, absorption, transmittance, reflectance behaviour and optical band gap values of CdO films were characterized by using X-ray diffraction (XRD), scanning electron microscopy and ultraviolet-visible spectroscopy techniques. XRD analysis reveals formation of CdO cubic crystalline structure. From these characterizations, it was seen that there are important distinctions in the structural, morphological and optical properties of undoped and K-, Li-and Na-doped nanostructured CdO films.

“…The Li-doped p-type ZnO thin films were grown by employing radio frequency magnetron sputtering [5][6][7][8]. The Li-, Na-, and K-doped ZnO nanoparticles were synthesized by the sol-gel method in a gelatin media by Yousefi et al [9]. The undoped and Li-doped ZnO crystallizes in the hexagonal symmetry with a wurtzite-like structure type [10].…”

In this study, attention was directed at the interactions between Li-doped ZnO systems and rye cereal. The interaction of cereal grains and straws with the transition metal ions is of biochemical importance primarily due to the presence of those complexes in biological systems. Metal/cereal chemistry plays a crucial role in the cross-linking of various biomolecules, and formed systems seem to be promising for various applications, such as material for the production of carbonizate and gaseous substances, which allows for the preparation of second generation biofuels. In the study of cereal/metal complexes, thermogravimetric measurements were performed in order to explain the influence of ZnO and Li 2x Zn 1-x O oxides on the thermal decomposition of rye grains in relation to their application for biofuel production. The possibility of generation of volatile products and carbonizate was considered. The characterization of carbonizate and volatile products was made. The catalytic properties of Li 2x Zn 1-x O phases in the decomposition of cereal grains were confirmed through thermal analysis. The thermal degradation of rye grains was catalyzed by Li-doped ZnO systems. Superior degradation to volatile products depended upon both the botanical origin of the cereal and the catalyzing system.
