Anisotropic Surface Melting of an Ice Crystal and Its Relationship to Growth Forms

摘要: Surface structures of ice crystals are discussed on the basis experiments and molecular dynamics simulation. Experimental results showed that anisotropic surface melting can occur {0001}- {1010}- faces an crystal at temperatures just below bulk point. Molecular simulations surfaces were also carried out in order to examine dynamic properties melting. Anisotropic temperature dependence thickness quasiliquid layer (qll), which was consistent with experimental results, confirmed between both {1010}-faces. Self-diffusion coefficients, estimated from translational movements water molecules layer, indicate change significantly changes depth qll surface. Finally, growth forms connection
