Quartz Crystal Microbalance Studies of Atomic-Scale FrictionJacqueline Krim, National Science Foundation, DMR0320743 Nanotribology Our research program is unique world-wide, exploring the nano- scale origins of friction with a quartz crystal microbalance technique that the PI developed in the late 1980’s with the support of NSF. This year we published the first systematic study of how atomic scale corrugation impacts sliding friction along interfaces of nano-technological interest. The results, published in the August 15, 2005 issue of Physical Review Letters, had been theoretical predicted for more than a decade, but heretofore unattainable by experiment. Upper: Artist’s rendition of the atomic vibrations that give rise to phononic friction, recently confirmed by our experiments. Lower: schematic of the quartz crystal oscillator technique employed by our research group.
Quartz Crystal Microbalance Studies of Atomic-Scale FrictionJacqueline Krim, National Science Foundation, DMR0320743 • DMR0320743 supports three graduate students and two undergrads, with strong representation from female and minority groups. Congratulations to Tonya Coffey, • (back row, far right), Ph.D. 2004 and Cherno Jaye (back row, far left), Ph.D. on track for December 2005. Krim’s feature article on atomic-scale friction was selected as the cover story for the February 2005 issue of Physics World.
