Title: Conclusive evidence of abrupt coagulation inside the void during cyclic nanoparticle formation in reactive plasma

Abstract

In this letter, we present scanning electron microscopy (SEM) results that confirm in a direct way our earlier explanation of an abrupt coagulation event as the cause for the void hiccup. In a recent paper, we reported on the fast and interrupted expansion of voids in a reactive dusty argon–acetylene plasma. The voids appeared one after the other, each showing a peculiar, though reproducible, behavior of successive periods of fast expansion, abrupt contraction, and continued expansion. The abrupt contraction was termed “hiccup” and was related to collective coagulation of a new generation of nanoparticles growing in the void using relatively indirect methods: electron density measurements and optical emission spectroscopy. In this letter, we present conclusive evidence using SEM of particles collected at different moments in time spanning several growth cycles, which enables us to follow the nanoparticle formation process in great detail.

  • An experimental investigation of an instability occurring during dust nanoparticle formation is presented in this paper. The present study has been performed in radio frequency low pressure plasma in an argon-silane mixture. The formation and growth of nanoparticles is followed, thanks to the analysis of the amplitude of the third harmonics (40.68 MHz) of the discharge current and the self-bias voltage (V{sub dc}). In some cases, at the end of the accumulation phase of the nanocrystallites an instability occurs. It seems to be an attachment induced ionization instability as observed in electronegative plasmas. A detailed study of the influence ofmore » different operating conditions (injected power, gas temperature, and silane flow rate) on this instability behavior and frequencies is presented. The paper concludes by examining a very particular case of the instability.« less
  • A quantitative measure of the rate at which fossil-pollen abundances changed over the last 18000 years at 18 sites spread across eastern North America distinguishes local from regionally synchronous changes. Abrupt regional changes occurred at most sites in late-glacial time (at {approx}13700, {approx}12300, and {approx}10000 radiocarbon yr BP) and during the last 1000 years. The record of abrupt late-glacial vegetation changes in eastern North America correlates well with abrupt global changes in ice-sheet volume, mountain snow-lines, North Atlantic deep-water production, atmospheric CO{sub 2}, and atmospheric dust, although the palynological signal varies from site to site. Changes in vegetation during mostmore » of the Holocene, although locally significant, were not regionally synchronous. The analysis reveals non-alpine evidence for Neoglacial/Little Ice Age climate during the last 1000 years, which was the only time during the Holocene when climate change was of sufficient magnitude to cause a synchronous vegetational response throughout the subcontinent. During the two millennia preceding this widespread synchronous change, the rate of change at all sites was low and the average rate of change was the lowest of the Holocene. 50 refs., 4 figs.« less
  • Reactive ion etching (RIE) of poly-{beta}-SiC was investigated in the NF{sub 3}/O{sub 2} mixture gas plasma. The addition of 10% oxygen concentration to the NF{sub 3} plasma increased the etching rate to {approx}80 nm/min at a total pressure of 10 Pa and 997 nm/min at a total pressure of 20 Pa. The ratio of increase in etching rate against that in the pure NF{sub 3} plasma was {approx}43%. RIE for longer than 30 min in the 90% NF{sub 3} and 10% O{sub 2} mixture gas plasma gave a much smoother surface than that etched in the pure NF{sub 3} plasma.more » However, the further addition of O{sub 2} decreased the etching rate. Optical-emission spectra indicated the presence of an oxygen radical, in addition to fluorine radical and molecular nitrogen cations, in the NF{sub 3}/O{sub 2} mixture gas plasma. X-ray photoemission spectroscopy analysis of the etched samples revealed that the SiO{sub 2} layer was formed on the surface at the higher O{sub 2} concentration. The role of oxygen in the NF{sub 3}/O{sub 2} mixture gas plasma was elucidated. Scanning electron microscopy observation revealed that many thornlike substances, i.e., spikes, were formed on the SiC surface during RIE at the total pressure of 10 Pa. Images of the cross section of spike formed during RIE at the total pressure of 2 Pa also indicated that the sputtered aluminum particle from a mask may be preferentially deposited on the top of carbon-rich island formed on the SiC surface and act as a micromask together with carbon on the carbon-rich island to form a thornlike spike. An etching model of the SiC surface and the mechanism on formation and growth of the spike on the SiC surface in the NF{sub 3}/O{sub 2} mixture gas plasma are proposed.« less
