“…As a new technical method breaking the diffraction limit, NSOM has been used in biology, materials science, surface chemistry and nonvisible wavelength instruments [31,32]. As for the nanomaterials science, NSOM was used to detect PL property of single nanostructure, and low temperature NSOM can dramatic increase the efficiency of an otherwise masked luminescence signal that may contain a wealth of information about the nanostructure [33][34][35].…”

“…NDPSs have recently attracted considerable attention because they show novel physical properties that lead to potentially unique applications in electronics, optoelectronics, and magnetic storage (Loo et al, 2002;Donthu et al, 2005;Chou et al, 1994Kong et al, 1997;Juang and Bogy, 2005). The mechanical properties of NDPSs and the associated tribological properties for potential applications in microelectro-mechanical systems (MEMS), however, have just started to be explored.…”

a b s t r a c tA numerical model was developed to simulate the nanoindentation of a Ni nanodot-patterned surface (NDPS) on a deformable Si substrate. Each contacting nanodot on the Si substrate was treated individually in this model and the interaction among the nanodots was considered through the elastic deformation of the Si substrate. The load-deformation relationship for the single-asperity contact between the indenter tip and a nanodot was determined using finite element analysis. A nanoindentation experiment on a Ni NDPS was performed to test the developed model. The simulation and experimental results were found to be in good agreement. The experimentally verified model was used to explore the effects of substrate deformation and surface roughness caused by the Ni nanodots on the nanoindentation behavior. It was found that the effect of the substrate and the effect of roughness must be considered. A detailed study of the substrate deformation shows that the interaction among nanodots, through the substrate, can contribute a considerable portion of the total deformation under a nanodot. The yield strength of the nanodot was found to have a significant effect on the contact deformation, while the elastic modulus was found to have little effect.

“…Fabrication of such nanodot arrays has attracted considerable recent attention because these nanostructures show novel physical properties that lead to potential unique applications in electronic, optoelectronics, and magnetic storage [1][2][3]. Many techniques, such as electron-beam, interference, imprint, and soft lithographies, as well as self-assembled anodic aluminum oxide (AAO) template methods, have been used to fabricate NDPS [4][5][6][7][8].…”

Ni nanodot-patterned surfaces for adhesion and friction reduction

et al. 2006

Surface nano-patterning with Ni nanodot arrays was investigated for adhesion and friction reduction of contacting interfaces. Self-assembled anodized aluminum oxide (AAO) templates in conjunction with thermal evaporation was used to fabricate nanopatterned surfaces with ordered Ni nanodot arrays on Si substrates. Surface morphology of the Ni nanodot-patterned surfaces (NDPSs) was characterized by scanning electron microscopy (SEM). Adhesion and friction studies on a Ni NDPS and a baseline smooth Si(100) surface were conducted using a TriboIndenter employing a diamond tip with 100 lm nominal radius of curvature. The results show that the ordered Ni nanodot-patterning reduced the adhesion forces and coefficients of friction up to 92 and 83%, respectively, compared to those of the smooth silicon surface. Surprisingly, the nanoscale multi-asperity contact between the diamond tip and inhomogeneous Ni NDPSs under low loads follows a continuum contact mechanics model.
