Van der Waals-induced chromatic shifts in hydrogen-bonded two-dimensional porphyrin arrays on boron nitride
(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 ...
The nucleation and early stages of layer-by-layer growth of metal organic frameworks on surfaces
(University of Nottingham, 2015-09-14)
High resolution atomic force microscopy (AFM) is used to resolve the evolution of crystallites of a metal organic framework (HKUST-1) grown on Au(111) using a liquid-phase layer-by-layer methodology. The nucleation and ...
Strain-engineered graphene grown on hexagonal boron nitride by molecular beam epitaxy
(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
(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 ...
Step-flow growth of graphene-boron nitride lateral heterostructures by molecular beam epitaxy
(The University of Nottingham, 2020-04-20)
Integration of graphene and hexagonal boron nitride (hBN) into lateral heterostructures has drawn focus due to the ability to broadly engineer the material properties. Hybrid monolayers with tuneable bandgaps have been ...
