Abstract

The authors developed a new apparatus that can measure lubrication film thickness accurately at the nanometer scale. Mica was used as a solid specimen and three kinds of liquids, i.e., octamethylcyclotetrasiloxane (OMCTS), cyclohexane and n-hexadecane were used as liquid specimens. From the ultrathin lubrication film thickness measurements using the apparatus, diseretization of the film thickness is observed for OMCTS and cyclohexane. The cause of the discretization is also discussed.
