Interaction between Iron and Graphene Nanocavity: Formation of Iron Membranes, Iron Clusters, or Iron Carbides

Motivated from a recent experimental study on filling of a graphene nanocavity by iron membrane at room temperature (<i>Science</i> <b>2014</b>, 343, 1228), we perform a comprehensive study of morphology changes of two-dimensional Fe membranes and iron carbides embedded in graphene nanocavities with specific sizes and shapes using the first-principles calculations and ab initio molecular dynamics simulations. Our simulations show that Fe atoms tend to gradually seal the graphene nanocavity via growing a metastable Fe membrane until the nanocavity is completely covered. Notably, a densely packed Fe membrane in the graphene nanocavity shows higher structural stability than a loosely packed one as long as more triangular lattices can form to release high tensile strain. The Fe membrane under high tensile strain tends to collapse and turns into a three-dimensional Fe cluster upon detaching from the edge. The structural transformation of Fe nanostructures follows the melting recrystallization mechanism at ambient temperatures in high vacuum. Moreover, the iron carbide can also exist in the graphene nanocavity and once formed can be highly stable even at 1200 K

Design of Ferroelectric Organic Molecular Crystals with Ultrahigh Polarization

Inspired by recent successful synthesis of room-temperature ferroelectric supramolecular charge-transfer complexes, i.e., tetrathiafulvalene (TTF)- and pyromellitic diimide (PMDI)-based crystals (Tayi et al.<i> Nature</i> <b>2012</b>, <i>488</i>, 485–489), three new ferroelectric two-component organic molecular crystals are designed based on the TTF and PMDI motifs and an extensive polymorph search. To achieve energetically favorable packing structures for the crystals, a newly developed computational approach that combines polymorph predictor with density functional theory (DFT) geometry optimization is employed. Tens of thousands of packing structures for the TTF- and PMDI-based crystals are first generated based on the limited number of asymmetric units in a unit cell as well as limited common symmetry groups for organocarbon crystals. Subsequent filtering of these packing structures by comparing with the reference structures yields dozens of promising crystal structures. Further DFT optimizations allow us to identify several highly stable packing structures that possess the space group of <i>P</i>2₁ as well as high to ultrahigh <i>spontaneous polarizations</i> (23–127 μC/cm²) along the crystallographic <i>b</i> axis. These values are either comparable to or much higher than the computed value (25 μC/cm²) or measured value (55 μC/cm²) for the state-of-the-art organic supramolecular systems. The high polarization arises from the ionic displacement. We further construct surface models to derive the electric-field-switched low-symmetry structures of new TTF- and PMDI-based crystals. By comparing the high-symmetry and low-symmetry crystal structures, we find that the ferroelectric polarization of the crystals is very sensitive to atomic positions, and a small molecular displacement may result in relatively high polarizations along the <i>a</i> and <i>c</i> axes, polarity reversal, and/or electronic contribution to polarization. If these newly designed TTF- and PMDI-based crystals with high polarizations are confirmed by experiments, the computer-aided ferroelectric material design on the basis of hydrogen-bonded charge-transfer complexes with flexible electron-donor and acceptor molecules would be proven valuable for expediting the search of room-temperature “displasive-type” ferroelectric organic crystals

Influence of Structural Fluctuations, Proton Transfer, and Electric Field on Polarization Switching of Supported Two-Dimensional Hydrogen-Bonded Oxocarbon Monolayers

The structural alignment, proton transfer, and molecular dipole under an electric field and as a function of simulation time have been investigated computationally for experimentally observed two-dimensional sheets of croconic acid (CA) on Ag(111) surface and rhodizonic acid (RA) molecules on Au(111) surface at room temperature. Depending on their local environment, some of the OH···O bonds in the CA monolayer exhibit spontaneous proton transfer especially for those bonds that are part of a trimer unit within the hydrogen-bonding network. In stark contrast, the RA molecules exhibit little proton transfer. It is found that thermal structural fluctuations of the molecular layers translate into considerable fluctuations of the polarization vector within the film plane, and even polarization reversal, at room temperature, which even can mask additional contributions to the polarization from the spontaneous and electric field induced proton transfer in CA monolayer. A common feature for both supported CA and RA monolayers is their constant polarization normal to the film plane

Similarity between Referents Constrains the Processing of Contrastive Focus during Reading

Contrastive focus implies a contrast between two elements. However, it is unclear whether and how any interplay between such a contrast and similarity between potentially contrasting elements might affect focus processing. Accordingly, we report an eye movement experiment investigating this issue. The experiment used a background story to introduce eight characters whose social identities were manipulated to be similar or dissimilar. Participants first read this background story, then a series of two-sentence discourses while their eye movements were recorded. Each discourse referred to two characters from the passage who had either similar or dissimilar identities, with one (the target character) either focused using the Chinese particle zhiyou (meaning only) or unfocused. The results showed a typical focus facilitation effect, such that target character names were processed more quickly when focused than unfocused. We also observed a main effect of the similarity / dissimilarly of characters and, crucially, an interaction between this variable and focus. This interaction was due to slower processing of a post-target region when the target character was focused and the two characters had similar rather than dissimilar identities, but no such effect when the target character was unfocused. The findings suggest that establishing a contrast between referents is effortful during reading when these have similar rather than dissimilar social identities and so are more difficult to differentiate. The distinctiveness of referents in a discourse context may therefore constrain the establishment of contrastive focus during reading. We discuss these findings in relation to current theories of focus interpretation

Surface Pseudorotation in Lewis-Base-Catalyzed Atomic Layer Deposition of SiO₂: Static Transition State Search and Born–Oppenheimer Molecular Dynamics Simulation

Atomic layer deposition (ALD) is a novel deposition technique for constructing uniform, conformal, and ultrathin films in microelectronics, catalysis, energy storage, and conversion. The possible reaction pathways for the uncatalyzed and catalyzed ALD of silicon dioxide (SiO₂) using SiCl₄ and H₂O have been investigated by density functional theory (DFT) calculations, combining static transition state searches with Born–Oppenheimer molecular dynamics (BOMD) simulations. In stepwise pathways of the uncatalyzed SiO₂ ALD reaction, the rate-determining step is the Si–O bond formation accompanied by the rotation of SiCl₄ with the activation free energy of 23.8 kcal/mol. The introduction of Lewis-base catalyst, pyridine or NH₃, can reduce the activation free energy to 6.8 or 2.7 kcal/mol. The low energy barrier and flexible pentacoordinated intermediate facilitate the surface pseudorotation (SPR) pathway, which is similar to Berry pseudorotation (BPR) pathway of the trigonal bipyramid (TBP) molecules, such as Fe­(CO)₅, SiCl₅^–, and PF₅. The catalyzed reaction may undergo multistep pathways, including adsorption of precursor, axial addition, surface pseudorotation, axial elimination, and desorption of byproduct steps. With one ligand pivot linked to the surface, the catalyzed reaction possesses three possible rotation modes. Through the low-barrier pseudorotation transition states, the axial angle changes from near 180° to 120° and the equatorial angle changes from 120° to near 180°, indicating the pairwise exchange of axial and equatorial ligands. The generality of Berry and surface pseudorotations with the characterized TBP topology exhibits the common fluxional behavior in pentacoordinated compounds containing main-group and metal elements. Useful information can be provided for ALD fabrication of various functional materials
