Title: Electron-beam-induced formation of Zn nanocrystal islands in a SiO{sub 2} layer

Abstract

Electron-beam-induced Zn nanocrystal islands were formed in a dielectric SiO{sub 2} layer. When a ZnO thin film on a p-type Si with amorphous SiO{sub x} interface layer is subjected to a 900 deg. C annealing followed by electron irradiation in a transmission electron microscope environment, an amorphous Zn{sub 2x}Si{sub 1-x}O{sub 2} layer is formed. Upon irradiation with a 300 keV electrons, metallic and single crystal nanoislands of Zn with {approx}7-10 nm diameter were formed and embedded within the SiO{sub 2} interface layer. Possible mechanisms for the formation of Zn nanocrystals are presented.

  • A densely stacked silicon nanocrystal layer embedded in a SiO{sub 2} thin film is synthesized with Si ion implantation. The dielectric functions of the nanocrystal layer are determined with spectroscopic ellipsometry. The dielectric functions show a significant suppression as compared to that of bulk crystalline Si. Thermal annealing leads to an evolution of the dielectric functions from the amorphous towards crystalline state. For an insufficient annealing, the dielectric functions present a single broad peak, being similar to that of amorphous Si. However, a sufficient annealing leads to the emergence of the two-peak structure which is similar to that of bulkmore » crystalline Si. In addition, the dielectric functions increase with annealing with a trend towards bulk Si.« less
  • The motivation of this work is the tailored growth of Ge nanocrystals for photovoltaic applications. The use of superlattices provides a reliable method to control the Ge nanocrystal size after phase separation. In this paper, we report on the deposition of (GeO{sub x}-SiO{sub 2}) superlattices via reactive dc magnetron sputtering and the self-ordered Ge nanocrystal formation during subsequent annealing. Attention is directed mainly to define proper deposition conditions for tuning the GeO{sub x} composition between elemental Ge (x=0) and GeO{sub 2} (x=2) by the variation in the deposition temperature and the oxygen partial pressure. A convenient process window has beenmore » found which allows sequential GeO{sub x}-SiO{sub 2} deposition without changing the oxygen partial pressure during deposition. The phase separation and Ge nanocrystal formation after subsequent annealing were investigated with in situ x-ray scattering, Raman spectroscopy, and electron microscopy. By these methods the existence of 2-5 nm Ge nanocrystals at annealing temperatures of 600-750 deg. C has been confirmed which is within the superlattice stability range. The technique used allows the fabrication of superlattice stacks with very smooth interfaces (roughness<1 nm); thus the Ge nanocrystal layers could be separated by very thin SiO{sub 2} films (d<3 nm) which offers interesting possibilities for charge transport via direct tunneling.« less
  • Nanometer scale patterns have been fabricated in SiO{sub 2} by electron beam exposure through a sacrificial layer. Although the process of patterning SiO{sub 2} with direct electron beam irradiation was discovered over two decades ago, the smallest feature size previously achieved was 0.6 {mu}m because finely focused electron beams form a contamination layer on the substrate blocking the subsequent development of the oxide with HF wet etches. Exposing through a sacrificial layer, the contamination is readily removed with the stripping of the sacrificial layer. Using high energy electrons (300 keV) to minimize forward scattering of the beam, arrays of linesmore » with a period down to 21 nm have been fabricated in the SiO{sub 2}.« less

Research highlights: {yields} SiO{sub 2} hollow particles with movable Fe{sub 3}O{sub 4} cores were obtained. {yields} Irradiation of electron beam induced the structural evolution. {yields} A new route to obtain hollow particles with movable core. -- Abstract: SiO{sub 2} hollow spheres with movable Fe{sub 3}O{sub 4} core were obtained by exposing the pre-synthesized Fe{sub 3}O{sub 4}/SiO{sub 2} particles (with an adsorption interlayermore » of ethylene glycol) under the irradiation of electron beam inside transmission electron micrograph (TEM). In the formation process, the evaporation of adsorbed ethylene glycol and the evolution of amorphous SiO{sub 2} layer played important roles, and that should be attributed to the high temperature and trapped charges induced by the irradiation of electron beam. This work provided a new route to obtain particles with movable core structure and extended the applications of electron beam.« less
  • Dewetting and nanopattern formation of 3{endash}10 nm Pt thin films upon ion irradiation is studied using scanning electron microscopy (SEM). Lateral feature size and the fraction of exposed surface area are extracted from SEM images and analyzed as functions of ion dose. The dewetting phenomenon has little temperature dependence for 3 nm Pt films irradiated by 800 keV Kr{sup +} at temperatures ranging from 80 to 823 K. At 893 K, the films dewet without irradiation, and no pattern formation is observed even after irradiation. The thickness of the Pt films, in the range 3{endash}10 nm, influences the pattern formation,more » with the lateral feature size increasing approximately linearly with film thickness. The effect of different ion species and energies on the dewetting process is also investigated using 800 keV Kr{sup +} and Ar{sup +} irradiation and 19.5keVHe{sup +}, Ar{sup +}, Kr{sup +}, and Xe{sup +} irradiation. The lateral feature size and exposed surface fraction scale with energy deposition density (J/cm2) for all conditions except 19.5keVXe{sup +} irradiation. {copyright} 2001 American Institute of Physics.« less
