5. 2D versus 3D competition at the early stages of growth for Ge on Si(001) by molecular dynamics

Author

Raiteri, P, Celino, M, Valentinotti, F, Miglio, L, MIGLIO, LEONIDA, Raiteri, P, Celino, M, Valentinotti, F, Miglio, L, and MIGLIO, LEONIDA

Abstract

The total energy of equilibrated pyramids layer by layer films and flat prepyramids in the epitaxial growth of Ge on Si (001) was investigated. Molecular dynamics (MD) simulations were applied to equilibrate the samples at atomic scale by the efficient code. It was shown that pyramids are more stable than Frank-van der Merwe (FM) films due to the partial strain relief.

Abstract

The injection of high-speed cryogenic pellets made of frozen hydrogen-isotopes, represents to date the most effective method to fuel magnetically confined thermonuclear fusion plasmas. Moreover, the injection of very large pellets composed of cryogenic solid of some suitable impurity (typically a noble-gas such as H2, Ne, or H2/Ne, D2/Ne mixtures), shattered in relatively small fragments just before entering the plasma, seems to be the most promising method to reduce the damage risks for the plasma-facing components in case of a plasma disruption. This technology, known as "Shattered Pellet Injection" (SPI), allows to spread out the plasma energy and mitigate possible damage to the in-vessel components, as well as to densify the plasma to suppress the formation of runaway electrons, and/or dissipate their energy. Several techniques to produce and launch cryogenic pellets have been investigated in the past decades. "Pipe gun" injectors are reliable and relatively simple devices are still commonly used today. They make use of single- or two-stage pneumatic light-gas guns to accelerate the pellet at high speeds. In these injectors, the cryogenic pellets are formed “in situ” (i.e., inside the launching barrel), by de-sublimating them directly from the gas phase, i.e., at temperatures and pressures below those of the triple point. The simplest case is pure deuterium pellets (T < 18.7 K, P < 171.3 hPa). The production of good quality solid deuterium, capable of withstanding the mechanical stress during the acceleration of the pellets, is a key issue. To this end the phase transition of deuterium from gas to solid (and vice versa) is modeled with extensive molecular-dynamics (MD) simulations. Moreover, the solid growth from the gas phase is simulated in an ample range of temperatures and pressures, to find the best compromise between growth velocity and mechanical properties of the resulting solid system.

Abstract

Corrosion property of iron in high temperature stagnant liquid lead has been studied using molecular dynamics method. The method was used to predict the limit values of the injected oxygen into the liquid lead for maximum corrosion inhibition of iron. It is from experimental results, in order to inhibit the corrosion at possible lowest rate then a stable self-healing protective iron oxide layer should be developed at the surface of steel continuously. In this research we investigated the iron corrosion and it can be predicted that the protective oxide layer may be formed by injecting oxygen within the range of 5.35 × 10-2 wt% to 8.95 × 10-2 wt% (for observed temperature 750 C). The oxygen 5.35 × 10-2 wt% is the lower limit to prevent high dissolution of iron while the oxygen content of 8.95 × 10-2 wt% is the upper limit to avoid high precipitation of lead oxide. We also guess that effect of oxygen injection into liquid lead creates a thin oxygen barrier that separating the liquid lead and iron oxides from direct interaction. The iron oxides layer and oxygen barrier then may be regarded as double corrosion inhibition. © 2013 Elsevier Ltd. All rights reserved.

14. Silicon diffusion in competitive TiSi2 phases by molecular dynamics simulations

Abstract

After a brief review of the basic properties of TiSi 2 phases recently obtained by molecular dynamics simulations, we show the self-diffusing species at high temperatures in both the C54 and C49 structures to be silicon, by hopping through a first neighbours network. The kinetic parameters and the diffusion paths for Si diffusion by vacancies and interstitials are reported, pointing out that diffusion in the C49 structure by SiI vacancies is strongly favoured, due to the very low formation energy they display.
