Zinc oxide films and nanomaterials for photovoltaic applications [[email protected]]

Aleksandra B. Djurišić, Xiang Liu, and Yu Hang Leung

pssr_zincIn this article, an overview of possible applications of ZnO in solar cells is provided. The simplest possible applications of Zn-based materials in solar cells are transparent contacts and light trapping/light scattering structures. This technology, compared to applications of ZnO in dye-sensitized and other types of solar cells as electron transport layer, is reasonably mature. The authors briefly summarize the results achieved and the potential for further development. In addition, they discuss the use of ZnO as electron transport layer in polymer and nanostructured (not including dye-sensitized) solar cells. The results achieved and unresolved problems are described. Finally, the use of ZnO in dye-sensitized solar cells is discussed. An overall future outlook for photovoltaic applications is briefly summarized.

Magnetization states and magnetization processes in nanostructures: From a single layer to multilayers [Feature Article]

Andrzej Maziewski, Jürgen Fassbender, Jan Kisielewski, Marek Kisielewski, Zbigniew Kurant, Piotr Mazalski, Feliks Stobiecki, Andrzej Stupakiewicz, Iosif Sveklo, Maria Tekielak, Andrzej Wawro, and Vitalii Zablotskii

pssa_MagnetizationMaziewski et al. present possibilities of engineering the magnetic properties (e.g. magnetic anisotropy and coercivity field) of nanostructures during deposition processes and post growth treatments, e.g. by ion irradiation and laser annealing. Magnetization distributions in single ultrathin layer and multilayers have been studied both experimentally (using Co films sandwiched between Au, Pt or Mo layers) and theoretically. Huge changes of these distributions, driven by the nanostructure geometry or the magnetic field, are shown.

Zinc oxide – From dilute magnetic doping to spin transport [Feature Article]

M. Opel, S. T. B. Goennenwein, M. Althammer, K.-W. Nielsen, E.-M. Karrer-Müller, S. Bauer, K. Senn, C. Schwark, C. Weier, G. Güntherodt, B. Beschoten, and R. Gross

pssb_ZincThe wide-bandgap semiconductor ZnO is a promising material with regard to dilute magnetic doping and spintronic applications. Opel et al. review the substitution with magnetic and non-magnetic ions, identify the formation of magnetic clusters, and demonstrate how extrinsic effects can obscure the magnetic measurements. The authors further demonstrate electrical spin injection into ZnO via optical and electrical detection schemes.
