Effect of Self-Assembled Monolayer Film Order on Nanofriction

July 6, 2006
Author(s)
S Sambasivan, S Hsieh, Daniel A. Fischer, Stephen M. Hsu
Friction at the nanoscale has become a significant challenge for microsystems, including MEMS, NEMS and other devices. At nanoscale, lateral loading often causes component breakage and loss of functions in devices, therefore, accurate measurement and
