The Adsorption of hexacontane on hexagonal boron nitride
(The University of Nottingham, 2018-11)We have investigated the adsorption of hexacontane (C60 H122) on hexagonal boron nitride (hBN) using atomic force microscopy (AFM). The molecules can be deposited either by sublimation or from solution and form lamellar ... -
Direct band-gap crossover in epitaxial monolayer boron nitride
(The University of Nottingham, 2019-06-28)Hexagonal boron nitride is a large band-gap insulating material which complements the electronic and optical properties of graphene and the transition metal dichalcogenides. However, the intrinsic optical properties of ... -
Fluorescence and electroluminescence of J-aggregated polythiophene monolayers on hexagonal boron nitride
(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 ... -
Moiré-modulated conductance of hexagonal boron nitride tunnel barriers
(The University of Nottingham, 2018-07-16)Monolayer hexagonal boron nitride (hBN) tunnel barriers investigated using conductive atomic force microscopy reveal moiré patterns in the spatial maps of their tunnel conductance consistent with the formation of a moiré ... -
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 ... -
Supramolecular heterostructures formed by sequential epitaxial deposition of two-dimensional hydrogen-bonded arrays
(The University of Nottingham, 2017-05-16)Supramolecular heterostructures are formed by growing sequential layers of bi- and mono-component two-dimensional molecular arrays stabilized by hydrogen bonding. The heterostructures are formed on hexagonal boron nitride ... -
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 ...
