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.
