    Description: Author(s): Haowei Peng, Zeng-Hui Yang, John P. Perdew, and Jianwei Sun Van der Waals interactions are ubiquitous in different materials yet not always described properly by current theories. Now, researchers have determined how to accurately and efficiently treat long-range Van der Waals interactions together with other chemical bonds, new findings that are important for studies of layered materials.

    Description: Author(s): Haowei Peng, Paul F. Ndione, David S. Ginley, Andriy Zakutayev, and Stephan Lany Although transition-metal oxides usually lack the combination of suitable band gaps and carrier transport properties desired for solar energy applications, such semiconducting properties can be realized in metastable MnO-ZnO alloys.

    Description: All-oxide photovoltaics could open rapidly scalable manufacturing routes, if only oxide materials with suitable electronic and optical properties were developed. SnO has exceptional doping and transport properties among oxides, but suffers from a strongly indirect band gap. Here, we address this shortcoming by band-structure engineering through isovalent but heterostructural alloying with divalent cations (Mg, Ca, Sr, and Zn). Using first-principles calculations, we show that suitable band gaps and optical properties close to that of direct semiconductors are achievable, while the comparatively small effective masses are preserved in the alloys. Initial thin film synthesis and characterization support the feasibility of the approach.
