Coordination complexes and polymers for advanced electronics
The field of coordination chemistry, pivotal in the synthesis of coordination complexes and polymers, offers unique pathways for enhancing electronic device performance. Coordination complexes consist of central metal atoms bonded to surrounding ligands, creating versatile structures whose physical and electronic properties can be finely tuned through the choice of metal and ligand components. This design flexibility is crucial for developing materials that meet specific requirements in advanced electronics. By manipulating the coordination environment, researchers can engineer complexes with desired conductivity, reactivity, and stability.
This tailorable nature of coordination complexes facilitates the design of innovative materials for a variety of electronic applications, ranging from semiconductors to sensors and light-emitting devices. This strong structure-property correlation inherent in coordination complexes not only broadens the scope of their application but also enables the precise engineering of materials to meet the evolving demands of the electronics industry.
Vapor-phase synthesis of large-scale two-dimensional materials
Two-dimensional (2D) materials, composed of atomically thin layers of crystalline compounds, have garnered significant attention as groundbreaking materials in recent years. Their extraordinary properties, which differ markedly from those of their three-dimensional counterparts, make them highly sought after for advanced applications.
Our research group has been actively engaged in the large-scale synthesis of two-dimensional materials, specifically graphene and transition metal dichalcogenides, using vapor-phase growth techniques. A focal point of our work is the innovative use of surface alloys both as reactants and as catalysts in the growth process. Noteworthy achievements include the direct growth of graphene on insulating substrates, facilitated by a surface alloy of Cu and Si that serves as a source of Cu catalyst vapor. Additionally, we have successfully achieved patterned growth of molybdenum disulfide on gold substrates, where a surface alloy of Au and Mo functions as an atomically thin reservoir of Mo, enabling precise material deposition.
