![]() But a significant controversy remains over the existence and impact of ferroelectricity on the photovoltaic response. Methylammonium lead iodide (MAPbI 3) exhibits exceptional photovoltaic performance. The Existence and Impact of Persistent Ferroelectric Domains in MAPbI 3 Ternary Nitride Semiconductors in the Rocksalt Crystal Structureĭiscovered new class of Mg xTM 1-xN ( TM = Ti, Zr, Hf, Nb) nitrides that bridges properties and structures found in common nitride materials families. Zn 2SbN 3 was theoretically predicted and experimentally synthesized-the first Sb-based nitride and a photoactive semiconductor. Revealing the metastable energy landscape of Pourbaix diagrams helps to rationalize multistage crystallization pathways of transition-metal oxides from solution.Ī Map of the Inorganic Ternary Metal NitridesĬonstructed first comprehensive stability map of inorganic ternary metal nitrides to understand chemical origins of stability and to predict new nitrides, along with corresponding synthetic routes to realize them.ĭiscovery of a Metastable Photoactive Semiconductor Zn 2SbN 3 Non-Equilibrium Crystallization Pathways of Manganese Oxides in Aqueous Solution Most of these highlights are associated with published journal articles by our principal investigators. The highlights here document the progress and impact of scientific research within the Center for Next Generation of Materials Design. ![]()
