Keeping the formation of lattice structures by nanoparticles covered with DNA in mind, we carry out Brownian dynamics simulations and study three-dimensional lattice structures formed by two species of particles. In our previous study [H. Katsuno, Y. Maegawa, and M. Sato, J. Phys. Soc. Jpn. 85, 074605 (2016)], we used the Lennard-Jones potential and studied two-dimensional structures formed in a binary system. When the interaction length between the different species, σ′, is shorter than that between the same species, σ, the lattice structure changes with the ratio σ′/σ. In this paper, we use the same potential and study the formation of three-dimensional structures. With decreasing ratio σ′/σ, the mixture of the face-centered-cubic (fcc) structure and hexagonal-close-packed (hcp) structure is changed to the bodycentered-cubic (bcc) structure and the NaCl structure. © 2017 The Physical Society of Japan.Embargo Period 12 month
