| Research Abstract |
A fabrication method of free-standing metal/ceramic nano-laminate thin film and its tensile testing technique was developed, and the deformation and fracture behavior of free-standing metal/ceramic nano-laminate thin film was investigated. The fracture toughness of Cu/Al_2O_3 laminated film with 5 layers (thickness: 500nm, Cu: 120nm, Al_2O_3: 60nm) was lower than that of Cu film (thickness: 500nm). However, Cu layer with a thickness of only 120nm in laminated film still caused plastic deformation. Moreover, we proposed a novel technique for the fabrication of laminated film with surface nanostructure.
