Graphene nanoribbons with hBN passivated edges grown by high-temperature molecular beam epitaxy (2023)
Journal Article

Integration of graphene and hexagonal boron nitride (hBN) in lateral heterostructures has provided a route to broadly engineer the material properties by quantum confinement of electrons or introduction of novel electronic and magnetic states at the...

Electroluminescence from a phthalocyanine monolayer encapsulated in a van der Waals tunnel diode (2023)
Journal Article

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.

Submolecular Resolution Imaging of P3HT:PCBM Nanostructured Films by Atomic Force Microscopy: Implications for Organic Solar Cells (2022)
Journal Article

The efficiency of organic bulk-heterojunction (BHJ) solar cells depends greatly on both the bulk and surface structure of the nanostructured bicontinuous interpenetrating network of materials, known as the active layer. The morphology of the top laye... Read More about Submolecular Resolution Imaging of P3HT:PCBM Nanostructured Films by Atomic Force Microscopy: Implications for Organic Solar Cells.

Natural optical activity as the origin of the large chiroptical properties in ?-conjugated polymer thin films (2020)
Journal Article

Polymer thin films that emit and absorb circularly polarised light have been demonstrated with the promise of achieving important technological advances; from efficient, high-performance displays, to 3D imaging and all-organic spintronic devices. How... Read More about Natural optical activity as the origin of the large chiroptical properties in ?-conjugated polymer thin films.

Triplet Excitation and Electroluminescence from a Supramolecular Monolayer Embedded in a Boron Nitride Tunnel Barrier (2019)
Journal Article

© 2019 American Chemical Society. We show that ordered monolayers of organic molecules stabilized by hydrogen bonding on the surface of exfoliated few-layer hexagonal boron nitride (hBN) flakes may be incorporated into van der Waals heterostructures...

Epitaxial multilayers of alkanes on two-dimensional black phosphorus as passivating and electrically insulating nanostructures (2019)
Journal Article

© The Royal Society of Chemistry. Mechanically exfoliated two-dimensional (2D) black phosphorus (bP) is epitaxially terminated by monolayers and multilayers of tetracosane, a linear alkane, to form a weakly interacting van der Waals heterostructure....

Ordering, Flexibility and Frustration in Arrays of Porphyrin Nanorings (2019)
Journal Article

The regular packing of atoms, molecules and nanoparticles provides the basis for the understanding of structural order within condensed phases of matter. Typically the constituent particles are considered to be rigid with a fixed shape. Here we show,... Read More about Ordering, Flexibility and Frustration in Arrays of Porphyrin Nanorings.

Ultra-high resolution imaging of thin films and single strands of polythiophene using atomic force microscopy (2019)
Journal Article

Real-space images of polymers with sub-molecular resolution could provide valuable insights into the relationship between morphology and functionality of polymer optoelectronic devices, but their acquisition is problematic due to perceived limitation...

The growth and fluorescence of phthalocyanine monolayers, thin films and multilayers on hexagonal boron nitride (2018)
Journal Article

Free-base phthalocyanine forms distinct interfacial phases and thin films on hexagonal boron nitride including a monolayer arrangement as determined using high resolution atomic force microscopy. The phases reveal significant differences in photolumi... Read More about The growth and fluorescence of phthalocyanine monolayers, thin films and multilayers on hexagonal boron nitride.

Substrate-induced shifts and screening in the fluorescence spectra of supramolecular adsorbed organic monolayers (2018)
Journal Article

We have investigated the influence of the substrate on the fluorescence of adsorbed organic molecules. Monolayer films of perylene-3,4,9,10-tetracarboxylic-3,4,9,10-diimide (PTCDI), a supramolecular network formed from PTCDI and melamine, and perylen...
