ABSTRACT
The growth and resulting crystallography of Cu nanowire arrays fabricated using glancing angle deposition are studied. On native oxide Si(100), the nanowires exhibited a strong (110) texture for a deposition angle θ=75° with rotational symmetry of the low energy Cu[111] about the long axis. On hydrogen-terminated Si(110), the wires are epitaxial with the substrate. The critical height for epitaxial growth is maximal at θ=35°, and decreases rapidly with increasing deposition angle. Based on the growth mechanisms in glancing-angle-deposited materials, the theory of growth mode in epitaxial thin films, and the observations about texture formation in epitaxial and nonepitaxial Cu nanowires; we discuss the observed growth modes in epitaxial nanowire arrays.

    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...

    ZnO will become a new pattern optoelectronic material because of its many excellent properties. But the defects in ZnO crystal are the key factors for restricting the luminescence properties of the material. In this paper, we summarized the defect types that exist in ZnO thin films and reviewed...

    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...

    It is shown that increasing external field stimulates appearance of the conductive microplasma channels in a-As2Se3 thin films. Cooling a sample under high field causes the disabling of microplasmas and decreases the sample conductance by several orders of magnitude in a rather narrow...
