PNNL

Dr. Chambers’ research interests at PNNL have focused on the deposition and properties of complex metal oxide films and heterostructures. Such materials are of significant interest in a variety of scientific and technological arenas, including oxide electronics and spintronics and energy conversion and storage. Of specific interest has been modification of electronic, magnetic, optical, and photochemical properties by controlled doping and solid solution formation, with an eye toward novel behavior that could give rise to new and useful technologies based on oxides. His film deposition methods of choice are molecular beam epitaxy and off-axis pulsed laser deposition, assisted by activated oxygen from an oxygen plasma generator.

He brings a variety of in situ and ex situ characterization methods to bear on these materials, including reflection high-energy electron diffraction, x-ray diffraction, high-resolution x-ray and ultraviolet photoelectron spectroscopy using both lab-based and synchrotron light sources, scanning transmission electron microscopy and related spectroscopies, atom probe tomography, and scanning probe microscopy. He also integrates a strong theoretical modeling component with his experimental efforts.

Details 

Before joining Pacific Northwest National Laboratory, Dr. Chambers was a staff scientist at the Boeing High Technology Center in Seattle. In that role, he conducted research in the epitaxial growth of intermetallic compounds on III-V compound semiconductors, in support of the development of advanced digital and analog devices for aerospace electronics applications. Prior to that he was Associate and Assistant Professor of Chemistry at Bethel University and George Fox University, respectively. 

He has authored or coauthored more than 365 peer reviewed scientific papers, review articles and book chapters with over 22,0000 citations and an h-index of 80 (Google Scholar). He has also given more than 235 invited lectures at universities, research laboratories and conferences worldwide. He holds three U.S. patents.
