The Correlation of Stress-State and Nano-Mechanical Properties in Au
FUNDAMENTALS OF NANOINDENTATION AND NANOTRIBOLOGY(2011)
摘要
A dependence of elastic response on the stress-state of a thin-film has been demonstrated using the interfacial force microscope (IFM). Indentation response was measured as a function of the applied biaxial stress-state for 100 nm thick Au films. An increase in measured elastic modulus with applied compressive stress, and a decrease with applied tensile stress was observed. Measurements of elastic modulus before and after applying stress were identical indicating that the observed change in response is not due to a permanent change in film properties.
