摘要：

A wedge-shaped iron (Fe) film system, quenched by silicone oil during deposition, has been prepared on glass substrates by direct current magnetron sputtering, and the influence of external disturbance on buckling patterns is investigated. The experiment shows that the wedge-shaped Fe film possesses a high compressive stress, which is relieved by spontaneous formation of telephone cord buckles in the atmosphere condition. The growth process can last several days to more than a month. When the film is disturbed by an external force, the stored stress energy will release drastically to form straight-sided buckles within several seconds. The morphological characteristics, edge effect and formation mechanism of the straight-sided buckles are discussed in detail.
