The components used in micro- and nanostructures are very light on the order of few micrograms and operate under very light loads on the order of few micrograms to a few milligrams . As a result friction and wear on a nanoscale of lightly loaded 1999 by CRC Press LLC micro nanocomponents are highly dependent on the surface interactions few atomic layers . These structures and magnetic storage devices are generally lubricated with molecularly thin films. Micro- and nanotribological techniques are ideal to study the friction and wear processes of micro- and nanostructures and molecularly thick lubricant films Bhushan et al. 1994a-e 1995a-g 1997a-c Koinkar and Bhushan 1996a b 1997a b 1998 Sundararajan and Bhushan 1998 . Although micro nanotribological studies are critical to study micro- and nanostructures these .
