Synthesis and Properties of Complex Crystalline and Glassy Metal Chalcogenides

Project: Research project

Project Details


The primary goals of this research are to discover and characterize new types of metal chalcogenide
compounds and to develop and understand their structures, chemical bonding and physical properties.
An important question of this synthesis program is whether we can guide the fundamental reaction
chemistry occurring in salt fluxes at intermediate temperatures to suppress the formation
of undesirable compounds and favor the crystallization of new ones. The project employs salt
flux syntheses to seek new materials novel structure and compositions. Well-defined building
blocks are present in the flux reactions and their formation is guided by tuning the flux
composition and temperature, which controls Lewis basicity and redox potential. In addition,
the salt fluxes can sustain tunable dynamic equilibria that are important for the synthesis
to be directed towards new materials. We hypothesize that manipulation of these flux properties
will allow the control of the synthetic routes toward a variety of new structures.
