Research Synopsis: Solid-State Chemistry: correlated electronic low-dimensional transition metal oxides and chalcogenides, superconductors, ionic conductors, catalysts for water oxidation


(848) 445-3277





Research Summary

Solid state inorganic chemistry; synthesis and crystal growth of novel transition metal compounds with quasi-low-dimensional properties including perovskite-related manganates, coboltates and ferrates with large magnetoresistant properties, transition metal (Mo, W, Nb) oxide bronzes, metal cluster chalcogenides, transition metal nitrides, and high temperature superconductors. Properties of compounds are characterized by X-ray diffraction, magnetic susceptibility, electronic conductivity, Seebeck effect, X-ray absorption near-edge spectroscopy, and thermal analysis. Structural-physicochemical property relationships are emphasized. Particular interest in compounds with electronic correlations/instabilities that lead to metal-to- insulator or metal-to-charge density wave, or superconducting transitions. Because of the highly aniosotropic behavior of low-dimensional materials, single crystal growth of bulk materials and films are pursued.
