Journal Article
Summerfield, A., Cebula, I., Schröder, M., & Beton, P. H. (2015). Nucleation and Early Stages of Layer-by-Layer Growth of Metal Organic Frameworks on Surfaces. Journal of Physical Chemistry C, 119(41), 23544-23551. https://doi.org/10.1021/acs.jpcc.5b07133

High resolution atomic force microscopy (AFM) is used to resolve the evolution of crystallites of a metal organic framework (HKUST-1) grown on Au(111) using a liquid-phase layer-by-layer methodology. The nucleation and faceting of individual crystall... Read More about Nucleation and Early Stages of Layer-by-Layer Growth of Metal Organic Frameworks on Surfaces.

van der Waals-induced chromatic shifts in hydrogen-bonded two-dimensional porphyrin arrays on boron nitride (2015)
Journal Article
Korolkov, V. V., Svatek, S. A., Summerfield, A., Kerfoot, J., Yang, L., Taniguchi, T., …Beton, P. H. (2015). van der Waals-induced chromatic shifts in hydrogen-bonded two-dimensional porphyrin arrays on boron nitride. ACS Nano, 9(10), https://doi.org/10.1021/acsnano.5b04443

The fluorescence of a two-dimensional supramolecular network of 5,10,15,20-tetrakis(4-carboxylphenyl)porphyrin (TCPP) adsorbed on hexagonal boron nitride (hBN) is red shifted due to, primarily, adsorbate–substrate van der Waals interactions. TCPP is... Read More about van der Waals-induced chromatic shifts in hydrogen-bonded two-dimensional porphyrin arrays on boron nitride.

High Broad-Band Photoresponsivity of Mechanically Formed InSe-Graphene van der Waals Heterostructures (2015)
Journal Article
Mudd, G. W., Svatek, S. A., Hague, L., Makarovsky, O., Kudrynskyi, Z. R., Mellor, C. J., …Patanè, A. (2015). High Broad-Band Photoresponsivity of Mechanically Formed InSe-Graphene van der Waals Heterostructures. Advanced Materials, 27(25), 3760-3766. https://doi.org/10.1002/adma.201500889

We exploit the broad-band transparency of graphene and the favorable band line up of graphene with van der Waals InSe crystals to create new functional heterostructures and high-performance photodetectors. The InSe-graphene heterostructure exhibits a... Read More about High Broad-Band Photoresponsivity of Mechanically Formed InSe-Graphene van der Waals Heterostructures.

Emergent Rhombus Tilings from Molecular Interactions with M-fold Rotational Symmetry (2015)
Journal Article
Whitelam, S., Tamblyn, I., Garrahan, J. P., & Beton, P. H. (2015). Emergent Rhombus Tilings from Molecular Interactions with M-fold Rotational Symmetry. Physical Review Letters, 114(11), Article 115702. https://doi.org/10.1103/PhysRevLett.114.115702

© 2015 American Physical Society. We show that model molecules with particular rotational symmetries can self-assemble into network structures equivalent to rhombus tilings. This assembly happens in an emergent way, in the sense that molecules sponta... Read More about Emergent Rhombus Tilings from Molecular Interactions with M-fold Rotational Symmetry.

Supramolecular nesting of cyclic polymers (2015)
Journal Article
Kondratuk, D. V., Perdigão, L. M., Esmail, A. M., O'Shea, J. N., Beton, P. H., & Anderson, H. L. (2015). Supramolecular nesting of cyclic polymers. Nature Chemistry, 7(4), 317-322. https://doi.org/10.1038/nchem.2182

Advances in template-directed synthesis make it possible to create artificial molecules with protein-like dimensions, directly from simple components. These synthetic macromolecules have a proclivity for self-organization that is reminiscent of biopo... Read More about Supramolecular nesting of cyclic polymers.

Ligand-Induced Control of Photoconductive Gain and Doping in a Hybrid Graphene–Quantum Dot Transistor (2015)
Journal Article
Turyanska, L., Makarovsky, O., Svatek, S. A., Beton, P. H., Mellor, C. J., Patanè, A., …Wilson, N. R. (2015). Ligand-Induced Control of Photoconductive Gain and Doping in a Hybrid Graphene–Quantum Dot Transistor. Advanced Electronic Materials, 1(7), 1500062. https://doi.org/10.1002/aelm.201500062

In graphene devices decorated with a layer of near-infrared colloidal PbS quantum dots (QDs), the choice of the QD capping ligands and the integrity of the QD layer have a strong influence on the doping, carrier mobility, and photoresponse. By using... Read More about Ligand-Induced Control of Photoconductive Gain and Doping in a Hybrid Graphene–Quantum Dot Transistor.
