“…[1][2][3][4] Of these forms, silica nanowires have a unique one-dimensional structure and properties with potential applications in nano-electromechanical systems, such as sensors and optical devices. [5][6][7] To facilitate the use of silica NWs in these devices, the mechanical properties and the associated phenomena which govern such nanostructures need to be well understood. Previous studies have utilized both experimental and theoretical approaches to investigate key mechanical and structural properties of amorphous silica NWs under tension and compression.…”

Shape memory effects and pseudoelasticity in bcc metallic nanowires J. Appl. Phys. 108, 113531 (2010) This study investigates the structural transformations and properties of silica glass nanowires under tensile loading via molecular dynamics simulations using the BKS (Beest-Kramer-Santen) interatomic potential. Surface states of the elongated nanowires were quantified using radial density distributions, while structural transformations were evaluated via ring size distribution analysis. The radial density distributions indicate that the surface states of these silica nanowires are significantly different than those of their interior. Ring size analysis shows that the ring size distributions remain mainly unchanged within the elastic region during tensile deformation, however they vary drastically beyond the onset of plastic behavior and reach plateaus when the nanowires break. The silica nanowires undergo structural changes which correlate with strain energy and ring size distribution variations. It is also found that the ring size distribution (and strain energy) variations are dependent on the diameter of the silica nanowires. Interestingly, for ultrathin nanowires (diameters < 5 .0 nm), the variation of ring size distributions shows a distinct trend with respect to tensile strain, indicating that the surface states play a key role in both modifying the mechanical properties and structural characteristics. These results for ultrathin nanowires are consistent with prior theoretical and simulation predictions. The overall findings in this study provide key insights into the novel properties of nano-sized amorphous materials, and are aimed to inspire further experiments. V C 2015 AIP Publishing LLC.

“…The properties of glass, especially the optical properties, can be tailored over wide ranges through careful compositional control, and glass can be readily manufactured into a wide variety of useful products, from large segments of a 100 m diameter primary telescope mirror 4 to nanometer-scaled fibers for photonic devices. 5 The flexibilities in compositional/property design and in manufacturing processes allow glasses to be considered for many engineering problems that are unsolvable by other materials.…”

“…Recently, silica and glass waveguides with diameters of submicrometer scale were developed and showed good light guiding ability. [3][4][5] Since the miniaturization limit of waveguides is dominated by diffraction limit λ/2n (λ: wavelength, n: refractive index of the core), 6 waveguides with a high refractive index are highly required for further miniaturization. Titanium dioxide (TiO 2 ) is one of the candidates for the microfabricated waveguides because of the high refractive index and good transparency from infrared to visible region.…”

An optical channel waveguide is a key solution to overcome signal propagation delay. For the benefits of miniaturization, development of microfabrication process for waveguides is demanded. TiO2 is one of the suitable candidates for the microfabricated waveguide because of the high refractive index and the transparency. In the present study, conventional microfabrication processes manufactured TiO2 channel waveguides with 1-20 μm width on oxidized Si substrates and the propagation loss was measured. The prepared channels successfully guided light of 632.8 nm along linear and Y-branched patterns. The propagation loss for the linear waveguide was 9.7 dB/cm
