ABSTRACT
We demonstrate that topographically modified substrates can be used as templates to control solid-state dewetting of thin films by creating a periodic variation in the initial curvature of the film. The dewetting of gold films on oxidized silicon surfaces patterned with arrays of inverted pyramid shaped pits is investigated. For specific ranges of relative film thickness and topographic dimension, dewetting results in arrays of submicrometer-scale particles with uniform periodic spacing and nearly uniform size and crystallographic orientation.

    Epitaxial growth of non-polar wurtzite (11-20) AlN thin films was achieved on a Si(100) substrate by inserting an MnS buffer layer. The a-plane AlN film and MnS buffer layer were fabricated by pulsed KrF excimer laser deposition, and their micro- and interfacial atomic structures were...

    We report 10-fold higher toughness at microcorrugated copper-silica interfaces than their planar counterpart and separate the contributions of adhesion, metal layer plasticity, and debond shielding. While corrugations parallel to the crack path toughen the interface due to debond area increase,...

    Pure Bi4Ti3O12 thin films with outstanding ferroelectric properties are reported. These films have been prepared by spin coating on substrates with a chemical solution. A (117)-preferred growth occurs at the annealing temperature of 600 °C. These films have a low coercive field of ∼35...

    The electro-optical response of calcium barium niobate ferroelectric thin films is characterized using a single beam setup in reflection geometry. Clear evidence of a Pockels response together with an r33 coefficient as high as 130 pm/V is found. This large value and the high Curie temperature...

    Measurements of the electro-optic coefficient, r33, of a zwitterionic organic chromophore are reported. Amorphous polycarbonate and chromophore were mixed and spin-processed to obtain host-guest polymer thin films for measurement with a Teng-Man modulation eillipsometer. After poling, the films...

    Nanowires of amorphous SiO2 were synthesized by thermal processing of a Si(100) substrate at 1100 °C in the presence of a nitrogen flow, and using a 15 nm thick high silicon-solubility Pd/Au film as a catalyst. The substrate itself was the only source of silicon for the nanowire growth. The...

    Porous low-dielectric constant (low-κ) SiCOH thin films deposited using a plasma-enhanced chemical-vapor deposition have been comprehensively characterized before and after exposure to a reactive-ion-etch-type plasma of N2 and H2 chemistry. The low-κ film studied in this work is a...

    A quantitative technique for mapping the elastic modulus, performed on organosilicate glass (OSG) thin films with different surface conditions, is described. This modulus mapping technique provides highly valuable information about the elastic properties at the near-surface region of the films....
