Research Interests:
Hayes has extensive experience in studying the atomic-scale structure of materials and in understanding the relationship between that structure and electronic or optical properties, with special emphasis on materials systems with lowered symmetry or lessened order. Of particular significance is his involvement over the past twenty years in x-ray absorption spectroscopy (XAS). He played a major role in developing our present theoretical understanding of XAS, in developing it as a probe of atomic-scale structure, and in its application to technologically interesting materials (e.g., see 1982 monograph in Solid State Physics series).
His recent research includes extensions of XAS data acquisition techniques to study the structure of Sn-related DX centers in (Al,Ga)As and of the liquid electrolyte/Cu monolayer/Pt interfacial region. His current research on the structure of CdS nanocrystals grown in glass is described below. He is also designing and constructing a high-intensity, high-resolution laboratory facility for x-ray absorption and scattering/diffraction studies of materials.
