Abstract

We investigate magnetron-sputtered "N3FC" diamond-like carbon films at the nanoscale using an in situ transmission electron microscopy sliding experiment. We measure the sliding-induced changes in sp3- and sp2-hybridized carbon using electron energy loss spectroscopy, taking into account the effect of the electron beam. The rate of the phase transformation from sp3 to sp2 bonding is quantified as being between 0.009% and 0.018% volume transformed per sliding pass.
