Fluorescence and electroluminescence of J-aggregated polythiophene monolayers on hexagonal boron nitride
Beton, Peter; Kerfoot, James (The University of Nottingham, 2020-09-15)The photophysics of a semiconducting polymer is manipulated through molecular self-assembly on an insulating surface. Adsorption of polythiophene (PT) monolayers on hexagonal boron nitride (hBN) leads to a structurally-induced ... -
Giant moiré patterns and lattice-matched epitaxial graphene grown
Summerfield, Alex; Davies, Andrew; Beton, Peter; Diez Albar, Juan; Thomas, James; Cheng, Tin s. (The University of Nottingham, 2018-01-01)Lattice-matched graphene on hexagonal boron nitride is expected to lead to the formation of a band-gap but requires the formation of highly strained material and has not hitherto been realised. We demonstrate that aligned, ... -
Strain-engineered graphene grown on hexagonal boron nitride by molecular beam epitaxy
Beton, Peter; Summerfield, Alex; Davies, Andrew (University of Nottingham, 2016-02-01)Graphene grown by high temperature molecular beam epitaxy on hexagonal boron nitride (hBN) forms continuous domains with dimensions of order 20 μm, and exhibits moiré patterns with large periodicities, up to ~30 nm, ... -
Triplet excitation and electroluminescence from a supramolecular monolayer embedded in a boron nitride tunnel barrier
Beton, Peter (The University of Nottingham, 2019-12-10)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 with ... -
Two-dimensional diffusion of excitons in a perylene diimide monolayer quenched by a fullerene heterojunction
Kerfoot, James (The University of Nottingham, 2019-05-09)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 ... -
Van der Waals-induced chromatic shifts in hydrogen-bonded two-dimensional porphyrin arrays on boron nitride
Beton, Peter (University of Nottingham, 2015-10-01)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 redshifted due to, primarily, adsorbate-substrate van der ...
