    Temperature effects on dislocation core energies in silicon and germanium

    Temperature effects on the energetics of the 90-degree partial dislocation in silicon and germanium are investigated, using non-equilibrium methods to estimate free energies, coupled with Monte Carlo simulations. Atomic interactions are described by Tersoff and EDIP interatomic potentials. Our results indicate that the vibrational entropy has the effect of increasing the difference in free energy between the two possible reconstructions of the 90-degree partial, namely, the single-period and the double-period geometries. This effect further increases the energetic stability of the double-period reconstruction at high temperatures. The results also indicate that anharmonic effects may play an important role in determining the structural properties of these defects in the high-temperature regime.Comment: 8 pages in two-column physical-review format with six figure

    A citricultura brasileira representa importante segmento do agronegócio, sendo São Paulo o estado que detém o primeiro lugar no ranking nacional da produção. Proporcionalmente à pujança da sua citricultura, ele também lidera nas ocorrências fitossanitárias, as quais têm comprometido a rentabilidade do setor.PDF. 158_11
