Chemistry of Materials and the ACS Division of Inorganic Chemistry are proud to announce Annalise Maughan (graduate student and first author, now a post-doc at NREL) and James Neilson (assistant professor and corresponding author) as the winners of the 2019 Chemistry of Materials Lectureship and Best Paper Award. The award honors not only their highly creative and insightful work but also the contributions of all the members of a strong interdisciplinary international collaboration.
The winning paper, “Anharmonicity and Octahedral Tilting in Hybrid Vacancy-Ordered Double Perovskites,” examines tin halide-based perovskites with varied cations, and connects the influence of these cations on conductivity and transport in these vacancy-ordered double perovskites. The paper also details the discovery of two new hybrid materials and illustrates the atomistic origin and impact of anharmonic lattice dynamics on the charge transport properties of hybrid perovskite halide semiconductors.
“This work extremely thorough study of these materials, starting with the synthesis of new compounds, accompanied by detailed X-ray diffraction and DFT calculations. “The strength of this work lies in the fundamental insights and generalizations that reveal just how remarkable the electronic properties of these perovskite materials are.”
All About the Team
The Chemistry of Materials Lectureship and Best Paper Award recognizes not only cutting edge, high-quality science, but also the critical team aspect of research, and celebrates the importance of all co-authors and their contributions.
“Anharmonicity and Octahedral Tilting in Hybrid Vacancy-Ordered Double Perovskites” is the result of collaboration between the Neilson Group (Colorado State University) and the Scanlon Group (University College London). This fruitful collaborative effort has resulted in four published papers, including this winning one, in Chemistry of Materials and the Journal of the American Chemical Society.
Maughan and Neilson will represent the entire team when they present their research at a half-day symposium and award ceremony this August during the 2019 Fall ACS National Meeting in San Diego, CA. Congratulations, once again, to Annalise Maughan, James Neilson, Alex Ganose, Andrew Candia, Juliette Granger, and David Scanlon!
