“…To avoid uncertainties in the clamped boundary condition, Mai et al deposited Pt pads at the clamped points of a ZnO nanobelt suspended over a trench on a substrate . As the deposited pads can provide near‐perfect clamping, the elastic modulus, strain and strain of the doubly clamped NW loaded at the midpoint can be estimated by,

Applications of nanowires into future generation nanodevices require a complete understanding of the mechanical properties of the nanowires. A great research effort has been made in the past two decades to understand the deformation physics and mechanical behaviors of nanowires, and to interpret the discrepancies between experimental measurements and theoretical predictions. This review focused on the characterization and understanding of the mechanical properties of nanowires, including elasticity, plasticity, anelasticity and strength. As the results from the previous literature in this area appear inconsistent, a critical evaluation of the characterization techniques and methodologies were presented. In particular, the size effects of nanowires on the mechanical properties and their deformation mechanisms were discussed.

“…The AFM‐based three‐point bending test has been used for characterizing the elastic modulus of various NWs, including Si, Ge, BN,LaB 6 , TiSi 2 , NiC, SiC, Na 4 Mn 9 O 18 , SiO 2 , SrB 2 O 4 , Co 3 O 4 /CoO, ZnO, and metallic glasses . A sharp AFM tip may cause damage to the NW being tested, as shown in Figure b.…”

“…This renders the ordinary TEM specimen preparation process, which involves mechanical grinding, and/or slicing, largely inapplicable to this class of alloys. Ordered titanium silicides such as TiSi 2 have found substantial applications in the semiconductor and aerospace industries (Zou et al, 2009). As a component in siliconrich Si-Ti eutectic alloys, the growth characteristics of TiSi 2 phase and its orientation relationship with the Si matrix would require investigation by TEM when the microstructural scale is sufficiently fine.…”

“…31 As a result, in the last two decades the development of nano-manipulation techniques based on focus ion beam technology (FIB-SEM), 32 electron microscopy (EM), 33 the integration of micro-electro-mechanical systems (MEMS) into electron microscopes, 34,35 and atomic force microscopy (AFM), enabled the mechanical characterization of NWs on a new level. For instance, the AFM-based three-point bending test has been used for characterizing the elastic modulus of various NWs, including Ag, 36 Si, 37 Ge, 38 TiSi 2 , 39 NiC, 40 SiC, 41 SiO 2 , 42 ZnO, 43 and CuO 44 and metallic glasses. 45 Alternatively, the contact resonance method in an AFM, has also become a popular non-destructive method to measure the elastic properties of NWs, such as ZnO 33,46 oxidized Si 47 and Si.…”
