Title: Three-dimensional self-organization of crystalline gold nanoparticles in amorphous alumina

Abstract

Multilayered heterostructures containing gold nanoparticles embedded in amorphous alumina matrices were deposited on silicon (001) substrates using pulsed laser deposition. The three-dimensional ordering of gold nanoparticles within these multilayered heterostructures was investigated using cross-sectional transmission electron microscopy and image Fourier transformation. Self-organization of gold nanoparticles along the vertical direction was observed in films grown at 20 and at 320 deg. C. Self-organization occurred by means of two different growth modes; both vertically correlated growth (top-on-top) and anticorrelated growth (top-on-middle) mechanisms were observed. The results of these studies suggest that the driving force for vertical ordering in this material is related to the long-range elastic interactions among the nanoparticles within the growing films.

  • A self-organized fringe pattern in a single amorphous mark of a GeTe thin film was formed by multiple femtosecond pulse amorphization. Micro Raman measurement indicates that the fringe is a periodic alternation between crystalline and amorphous phases. The period of the fringe is smaller than the irradiation wavelength and the direction is parallel to the polarization direction. Snapshot observation revealed that the fringe pattern manifests itself via a complex but coherent process, which is attributed to crystallization properties unique to a nonthermally amorphized phase and the distinct optical contrast between crystalline and amorphous phases.
  • Certain objections regarding the article of Horiuchi and Sato (Phys. Fluids 29, 1161 (1986)) are presented. One class of objections is technical and the second concerns matters of attribution.
  • A three-dimensional self-organization process of a compressible dissipative plasma with a velocity-magnetic field correlation is investigated in detail by means of a variational method and a magnetohydrodynamic simulation. There are two types of relaxation, i.e., fast relaxation in which the cross helicity is not conserved and slow relaxation in which the cross helicity is conserved approximately. In the slow relaxation case the cross helicity consists of two components with opposite sign that have almost the same amplitude in the large wavenumber region. In both cases the system approaches a high correlation state, dependent on the initial condition. These results aremore » consistent with observational data of the solar wind. Selective dissipation of magnetic energy, normal cascade of magnetic energy spectrum, and inverse cascade of magnetic helicity spectrum are observed for the sub-Alfvenic flow case, as was observed previously for the zero-flow case. When the flow velocity is super-Alfvenic, the relaxation process is altered significantly from the zero-flow case.« less
  • A three-dimensional self-organization process in an incompressible dissipative plasma is investigated by means of a magnetohydrodynamic simulation. Two typical phases are observed, i.e., the energy-relaxation phase and the inverse-cascade phase. In the relaxation phase the total magnetic energy rapidly decreases while the magnetic structure is transformed into a simpler one by magnetic reconnection. In the inverse-cascade phase the magnetic helicity spectrum shifts towards the low-wave-number region while the magnetic energy spectrum shifts towards the high-wave-number region.
  • A three-dimensional self-organization process in an incompressible dissipative plasma is investigated in detail by means of a magnetohydrodynamic simulation. In an initial phase the total magnetic energy rapidly decreases via magnetic reconnection driven by a global ideal unstable mode, while the total magnetic helicity decreases very slowly throughout the simulation run. This selective dissipation is found to be caused by the excitation of nonhelical, small spatial scale structures of the magnetic field (''magnetic bubble'') in the vicinity of the reconnection points. Magnetic reconnection takes place at minimum points of the magnetic helicity density where the magnetic bubbles are predominantly created.more » The disappearance of the bubbles leads to a rapid dissipation of the total magnetic energy. While the magnetic helicity is globally conserved during this process, its spectral density is transferred to the low wavenumber region (''inverse cascade''). After the rapid dissipation of the magnetic energy, the magnetic configuration adjusts itself to a stable equilibrium with a minimum energy without any drastic decrease in the magnetic energy and helicity. The final stable state takes either an axially symmetric configuration or a helically symmetric configuration depending on the initial condition, which is in good agreement with the relaxation theory.« less
