Resonant tunnelling into the two-dimensional subbands of InSe layers (2020)
Journal Article
Kudrynskyi, Z. R., Kerfoot, J., Mazumder, D., Greenaway, M. T., Vdovin, E. E., Makarovsky, O., …Patanè, A. (2020). Resonant tunnelling into the two-dimensional subbands of InSe layers. Communications Physics, 3(1), https://doi.org/10.1038/s42005-020-0290-x

Two-dimensional (2D) van der Waals (vdW) crystals have attracted considerable interest for digital electronics beyond Si-based complementary metal oxide semiconductor technologies. Despite the transformative success of Si-based devices, there are lim... Read More about Resonant tunnelling into the two-dimensional subbands of InSe layers.

Triplet Excitation and Electroluminescence from a Supramolecular Monolayer Embedded in a Boron Nitride Tunnel Barrier (2019)
Journal Article
Svatek, S. A., Kerfoot, J., Summerfield, A., Nizovtsev, A. S., Korolkov, V. V., Taniguchi, T., …Beton, P. H. (2020). Triplet Excitation and Electroluminescence from a Supramolecular Monolayer Embedded in a Boron Nitride Tunnel Barrier. Nano Letters, 20(1), 278-283. https://doi.org/10.1021/acs.nanolett.9b03787

© 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...

Two-Dimensional Diffusion of Excitons in a Perylene Diimide Monolayer Quenched by a Fullerene Heterojunction (2019)
Journal Article
Kerfoot, J., Korolkov, V. V., Svatek, S. A., Alkhamisi, M., Taniguchi, T., Watanabe, K., …Beton, P. H. (2019). Two-Dimensional Diffusion of Excitons in a Perylene Diimide Monolayer Quenched by a Fullerene Heterojunction. Journal of Physical Chemistry C, 123(19), 12249-12254. doi:10.1021/acs.jpcc.9b01413

The structural and functional properties of organic heterojunctions play a vitally important role in the operation of organic devices, but their properties are difficult to measure directly due to the buried interfaces which are typically formed. We... Read More about Two-Dimensional Diffusion of Excitons in a Perylene Diimide Monolayer Quenched by a Fullerene Heterojunction.

The growth and fluorescence of phthalocyanine monolayers, thin films and multilayers on hexagonal boron nitride (2018)
Journal Article
Alkhamisi, M., Korolkov, V. V., Nizovtsev, A. S., Kerfoot, J., Taniguchi, T., Watanabe, K., …Beton, P. H. (2018). The growth and fluorescence of phthalocyanine monolayers, thin films and multilayers on hexagonal boron nitride. Chemical Communications, 54(85), 12021-12024 . doi:10.1039/C8CC06304D

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
Kerfoot, J., Korolkov, V. V., Nizovtsev, A. S., Jones, R., Taniguchi, T., Watanabe, K., …Beton, P. H. (2018). Substrate-induced shifts and screening in the fluorescence spectra of supramolecular adsorbed organic monolayers. Journal of Chemical Physics, 149(5), doi:10.1063/1.5041418. ISSN 0021-9606

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...

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), doi: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.
