Research Interests

Ross Datars' undergraduate work was done at McMaster and his graduate work was at the University of Wisconsin, graduating with a Ph.D. in 1959. After three years at the Defence Research Telecommunications Establishment in Ottawa, he joined the faculty of McMaster in 1962. He held the E.W.R. Steacie Research Fellowship from the Natural Sciences and Research Council for two years. He is a Fellow of the Royal Society of Canada and the American Physical Society.

The research of Dr. Datars deals with the electron properties of metals. They include C₆₀ fulleride compounds, intercalated graphite compounds, metal and polymer nanowires and light emitting organic devices. The techniques that are employed are the de Haas-van Alphen effect, the Hall effect, resistivity, far infrared spectroscopy and x-ray and neutron diffraction

Current research includes studies of magnetic bromides intercalated in graphite by using neutron diffraction, resistivity and magnetization measurements, nanowires of bismuth and polypyrrole with nanometer dimensions embedded in porous substrates and nuclear magnetic resonance of fulleride compounds formed from C₆₀ and Lewis acids.

There is a continuing program to prepare new materials that are useful for fundamental studies and applications in nanotechnology and devices.
