Atomic self-assembly of the random system into a stably triangular lattice

摘要

In this paper, we use molecular dynamics (MD) simulations to relax the initially random system into a triangular lattice. The initial system contains 900 atoms that interact with each other via the interaction potential established by Rechtsman et al. (Phys. Rev. Lett. 95, 228301 (2005)). Our results show that the targeted lattice is stable via relaxation time at low to high temperature, i.e. T = 0.1, T = 1.0 and T = 2.0, instead of zero temperature in previous results. Seeking targeted structures at high temperatures is a vital demand of materials applications. We also find that quality of the obtained lattice depends on relaxation temperature of the system.
