Research:
Surface chemistry
Surface chemistry is the focus of experimental work being
done in my laboratory, in particular the kinetics and spectroscopy
of species chemisorbed on well-characterized semiconductor,
metal and insulator surfaces. Interest is focused on molecular
level questions regarding the structure and reactivity
of species important in chemical reactions that are important
for catalysis and film growth.
In approaching these problems, White group students use
ultra-high vacuum (10-10 Torr), optical spectroscopy, scanning
probe microscopy spectroscopy, mass spectrometry, environmental
scanning electron microscopy and electron diffraction techniques.
High resolution electron energy loss spectroscopy and IR
are used to characterize the vibrational structure of chemisorbed
species. Auger, X-ray and ultraviolet photoelectron spectroscopy
are used to detail the kind of species present and the
chemical environment. Mass spectrometry, including Fourier
transform and secondary ion, are used to characterize fragments
ejected from the surface by ions, electrons or photons.
Photon- and electron-driven surface reactions are topics
of current focus. Interfacial force microscopy is used
to probe the mechanical properties of films with nanometer
resolution.
We have a particular interest in the chemical dynamics
and kinetics of molecules used in the growth of thin films
for electronic and opto-electronic structures and devices.
