(a) Hillock height h as a function of number of scratching cycles N, applied normal load Fn, and sliding velocity v [26]. (b) AFM images and corresponding cross-sectional profiles of friction-induced hillocks on silicon and quartz surfaces before and after washing [47]. (c) AFM images of various protrusive nanostructures (i.e., nanodots, surface isolated mesa, nanoline array, and pattern of “TRI”) produced by reciprocating scratching on silicon surface [24]
