Research Interests

UHV surface science: Ultrahigh vacuum techniques such as Auger electron spectroscopy, temperature programmed desorption monitored by a quadrupole mass spectrometer, and reflectance-absorbance infrared spectroscopy are used to investigate the interaction of molecules with well-characterized surfaces. Currently, we are investigating the interaction of amine-quinone compounds with iron surfaces. These molecules are models of corrosion inhibitors.

Thin film tribology: Tribology is the study of friction, lubrication, and wear. We are interested in the relationship between the structure of boundary layer (monolayer) lubricants and their frictional properties. We use a sensitive pin-on-disk type tribometer to rub surfaces with well-characterized, self-assembled monolayers and then analyze the surface spectroscopically. We are also working on metal/organic thin films with unique mechanical, structural, and optical properties.

Surface chemistry: As an aid to both of the above research thrusts, we use solution and vacuum phase reactions to make novel surfaces. Current work includes attachment chemistry on technologically important oxides (particularly silica and alumina) and fundamental study of the acid/base characteristics of such surfaces.

Experimental Methods Include:

• FT-IRAS: Fourier-transform infrared reflection-absorption spectroscopy
• TPD: Temperature Programmed Desorption (Mass Spectrometry)
• AES: Auger Electron Spectroscopy
• XPS: X-ray Photoelectron Spectroscopy
