2D And 3D

Emergence of a large variety of self-assembled superlattices is a dramatic recent trend in the fields of nanoparticle and colloidal sciences. Motivated by this development, we propose a model that combines simplicity with a remarkably rich phase behavior applicable to a wide range of such self-assembled systems. Those systems include nanoparticle and colloidal assemblies driven by DNA-mediated interactions, electrostatics, and possibly, controlled drying. In our model, a binary system of large and small hard spheres (L and S, respectively) interacts via selective short-range (“sticky”) attraction. In its simplest version, this binary sticky sphere model features attraction only between S and L particles. We show that, in the limit when this attraction is sufficiently strong compared with kT, the problem becomes purely geometrical: the thermodynamically preferred state should maximize the number of LS contacts. A general procedure for constructing the phase diagram as a function of system composition f and particle size ratio r is outlined. In this way, the global phase behavior can be calculated very efficiently for a given set of plausible candidate phases. Furthermore, the geometric nature of the problem enables us to generate those candidate phases through a well-defined and intuitive construction. We calculate the phase diagrams for both 2D and 3D systems and compare the results with existing experiments. Most of the 3D superlattices observed to date are featured in our phase diagram, whereas several more are predicted for future discovery.

New Generation

The engineering of a new generation of advanced materials based on nanoparticles demands the fabrication of self-assembled arrays of passivated metal, oxide and semiconductor clusters (1 -). In particular the case of self-assembled gold clusters passivated with an organic molecule has attracted the attention of several researchers (2-3). Because its unique properties gold metal is a leading candidate for the fabrication of single electron tunneling devices.Passivated gold nanoclusters were produced using the method developed by Brust et.al. (4) with the modifications of Whetten et.al (5) n-alkylthiol molecules were used as passivating agent. Carbon chains from C=4 to C=18 were used. It was found that C=12 dodecanethiol was optimum for forming ordered arrays of the clusters. To produce the superlattice crystallization a toluene vapor atmosphere was used. The passivated clusters were deposited on a copper electron microscope grid covered with carbon.
