Tayo research

Research in my group involves the use of various theoretical and computational tools for studying the properties of advanced materials for a wide range of applications including solar energy harvesting, energy storage, sensor applications, high speed electronics, optoelectronics, and renewable energy. We develop simple theoretical models as well as utilize standard computational materials science software packages to study the structural, electronic, optical, electrochemical, and electrocapacitive properties of different novel materials. The purpose of such studies is to predict important materials properties, as well as shed useful insights that can explain experimental observations or guide experimental development. Most of the materials that we study are also currently being investigated by our experimental collaborators. Such a collaboration provides a useful scheme that allows comparison of theoretical calculations with experimental findings with the goal of complementing the two approaches. Ongoing research projects involve four important classes of materials: carbon-based nanomaterials; two-dimensional atomic crystals and their heterostructures; ferrocene-containing organometallic polymers; and bulk transition-metal sulfides. Our group maintains collaborations with the Chemistry department at Pittsburg State University as well as other experimental and theoretical groups at the University of Kansas and Tulsa University.
