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 ... -
Resonant tunnelling into the two-dimensional subbands of InSe layers
Kudrynskyi, Zakhar; Patane, Amalia (The University of Nottingham, 2020-01-20)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 ... -
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 ...
