Giant moiré patterns and lattice-matched epitaxial graphene grown
(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, ...
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, ...
Quantum confinement and photoresponsivity of β-In2Se3 nanosheets grown by physical vapour transport
(University of Nottingham, 2016-06-01)
We demonstrate that β-In2Se3 layers with thickness ranging from 2.8 – 100 nm can be grown on SiO2/Si, mica and graphite using a physical vapour transport method. The β-In2Se3 layers are chemically stable at room temperature ...
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 ...
