Electroluminescence from a phthalocyanine monolayer encapsulated in a van der Waals tunnel diode (2023)
Journal Article
James, T., Bradford, J., Kerfoot, J., Korolkov, V. V., Alkhamisi, M., Taniguchi, T., …Beton, P. H. (2023). Electroluminescence from a phthalocyanine monolayer encapsulated in a van der Waals tunnel diode. Molecular Physics, 121(7-8), Article e2197081. https://doi.org/10.1080/00268976.2023.2197081

Monolayers of free base phthalocyanine (H2Pc) are grown on monolayer and few-layer exfoliated flakes of hexagonal boron nitride (hBN) which are subsequently integrated into a van der Waals tunnel diode. This heterostructure consists of two thin hBN f... Read More about Electroluminescence from a phthalocyanine monolayer encapsulated in a van der Waals tunnel diode.

Adsorbate-induced curvature and stiffening of graphene (2014)
Journal Article
Svatek, S. A., Scott, O. R., Rivett, J. P., Wright, K., Baldoni, M., Bichoutskaia, E., …Beton, P. H. (2015). Adsorbate-induced curvature and stiffening of graphene. Nano Letters, 15(1), https://doi.org/10.1021/nl503308c

The adsorption of the alkane tetratetracontane (TTC, C44H90) on graphene induces the formation of a curved surface stabilized by a gain in adsorption energy. This effect arises from a curvature-dependent variation of a moiré pattern due to the mismat... Read More about Adsorbate-induced curvature and stiffening of graphene.

Mechanical stiffening of porphyrin nanorings through supramolecular columnar stacking (2013)
Journal Article
Svatek, S. A., Perdigão, L. M., Stannard, A., Wieland, M. B., Kondratuk, D. V., Anderson, H. L., …Beton, P. H. (2013). Mechanical stiffening of porphyrin nanorings through supramolecular columnar stacking. Nano Letters, 13(7), https://doi.org/10.1021/nl4017557

Solvent-induced aggregates of nanoring cyclic polymers may be transferred by electrospray deposition to a surface where they adsorb as threedimensional columnar stacks. The observed stack height varies from single rings to four stacked rings with a l... Read More about Mechanical stiffening of porphyrin nanorings through supramolecular columnar stacking.
