The geometric blueprint of perovskites [PDF]
Proceedings of the National Academy of Sciences, 2018 Significance Perovskites constitute one of the most versatile and chemically diverse families of crystals. In perovskites the same structural template supports a staggering variety of properties, from metallic, insulating, and semiconducting behavior to superconducting, ferroelectric, ferromagnetic, and multiferroic phases.

Curtailing Perovskite Processing Limitations via Lamination at the Perovskite/Perovskite Interface [PDF]
ACS Energy Letters, 2018 Standard layer-by-layer solution processing methods constrain lead–halide perovskite device architectures. The layer below the perovskite must be robust to the strong organic solvents used to form the perovskite while the layer above has a limited thermal budget and must be processed in nonpolar solvents to prevent perovskite degradation. To circumvent
