Tensile testing of a diamond-like carbon (DLC) thin film was carried out by using the originally developed nano-materials testing system (NTS) that consisted by a nano-materials tester and a scanning electron microscope. This experiment is the first step for the formation of graphene by stress-induced transformation of an amorphous carbon film. The study may lead us to new findings of unique properties in a transient state of carbons. Stress-strain curve of the DLC film showed that tensile strength and Young's modulus of the film were approximately 420 MPa and 110 GPa, respectively. To evaluate performance of the NTS, a nano-indentation test was carried out for the same sample. Mechanical properties obtained by NTS were mostly in agreement with that of the indentation test. These experimental results demonstrated that the NTS would be one of the effective testing methods to evaluate the mechanical characteristics of DLC thin films.
