“…The split of the second peak indicates that the confined solid is amorphous [20]. The detailed discussion on the atomic structure is given in elsewhere [19]. The comparison of our results with experimental results are also given in elsewhere [18].…”

“…Under this free boundary condition, particles on the surface can easily move. Therefore, rearrangement of particles can frequently occur, compared with periodic boundary conditions or a system confined in a small space [19], and cystallization will proceed more quickly and smoothly. We observed the structural transformation in real space as a function of observation time.…”

Abstract:A monatomic simple liquid in two dimensions, where atoms interact isotropically through the LennardJones-Gauss potential [M. Engel, H.-R. Trebin, Phys. Rev. Lett. 98, 225505 (2007)], is vitrified by the use of a rapid cooling technique in a molecular dynamics simulation. Transformation to a crystalline state is investigated at various temperatures and the time-temperature-transformation (TTT) curve is determined. It is found that the transformation time to a crystalline state is the shortest at a temerature 14% below the melting temperature T and that at temperatures below T ≡ 0 6T the transformation time is much longer than the available CPU time. This indicates that a long-lived glassy state is realized for T ≤ T .
