“…On the basis of previous reports, the mechanisms for the size effect of graphene interface are analyzed as follows. The specific microstructure and roughness of the substrate surface are two essential factors that lead to the size effect of graphene . The final configuration between the graphene and the substrate depends on the micro-sized roughness and the length of graphene. , The shorter is the length of graphene and the smoother is the surface of substrate, the easier a full conformation and better bond at the interface can be achieved.…”

“…When the size of graphene reaches the micrometer level, the surface energy will be dramatically affected by the surface effect. Other factors, such as the boundary configuration, the scattering effect and adsorbates in the fringe areas, surface dangling-bonds, and vibrational dissipation of the edge atoms, are also potential reasons …”

“…Other factors, such as the boundary configuration, the scattering effect and adsorbates in the fringe areas, surface dangling-bonds, and vibrational dissipation of the edge atoms, are also potential reasons. 32 Table 1 presents the experimental results of the eight specimens, including six interfacial mechanical parameters, which are the substrate debonding strain (ε smax ), graphene maximum strain (ε gmax ), interface limit strain (ε imax ), CT length (L ct ), CRT length (δ), and interface strength (τ c ). The parameters in the first three columns are size-independent, while the parameters in the last three columns are sizedependent.…”

The size effect and deformation transfer of the interface between graphene and a polymer substrate are experimentally investigated. Eight composite specimens, containing polyethylene terephthalate substrate (PET) and eight different sizes of graphene, are designed. The specimens are studied by a series of experiments to explore how the mechanical properties of the tangential interface between graphene and the substrates can be influenced by the size of graphene. Micro-Raman spectroscopy is employed to measure the full-field strain of graphene subjected to a uniaxial tensile loading process, based on which the evolution of the bonding states of the interface is obtained. The existence of a size effect in the interfacial strain transfer process at the graphene/PET interface is observed, and this phenomenon is characterized by a size threshold and an innovatively defined parameter called the critical relative transfer length. Combined with previous experimental results on the tangential interface of graphene, we observe that the size effect of the interfacial shear stress of graphene is the main cause for the inconformity of experimental data published in previous reports.

“…Recently, it was shown that Al-(1 wt%)Cu thin films, processed in a MEMS fabrication line, exhibit a significant time-dependent anelastic deformation recovery after unloading over a period of days [7,8]. It has been hypothesized that this behavior is related to the precipitation state [9,8]. Investigating the precipitation hardening behavior in these thin films is es sential to assess possible deformation mechanisms relevant to MEMS device reliability.…”
