    Current Research

    Our research program focuses on surface and interface science. The beauty of this discipline is in its links with analytical, organic, and inorganic chemistry. Using the techniques and methods of physical chemistry, we solve problems related to chemical transformations of organic and organometallic compounds on semiconductors, thin solid film growth and etching, nanostructure and nanomaterial formation. We study these processes at the molecular level with vibrational spectroscopies, high-energy electron spectroscopies, mass spectrometry, X-ray spectroscopies, microscopic techniques and supplement these experimental studies with computational investigations

    Current research projects include chemical modification of semiconductor surfaces to tune their physical (band alignment and bending, charge carrier properties) and chemical (functionalization, passivation) properties to adjust those to a specific application. The goal of this research direction is to develop new strategies for manipulating the surface properties of semiconductor materials in a controlled way. The findings of these investigations will be relevant for future applications in molecular and nanoelectronics, sensing, and solar energy conversion.

    We are also interested in covalent attachment of large molecules and nanoparticles to surfaces to yield novel interfaces, thin films, and materials. We have used C60 Buckminster fullerenes and their derivatives as well as carbon nanotubes as spectroscopic and microscopic probes to establish the covalent nature of their binding to appropriately terminated self-assembled monolayers on silicon. More recently, we have also investigated the possibility of designing new approaches to layer-by-layer growth of nanoparticle thin films leading to exceptionally high coverages based on covalent attachment rather than self-assembly.

    Other projects include metalorganic reactions for controlled deposition and atomic layer etching (layer-by-layer removal of metals from thin films), deposition of thin solid films used as hard coatings, and multivariate curve resolution of complex thermal desorption data.
