Molecular quantum ring formed from a pi-conjugated macrocycle
(The University of Nottingham, 2020-10-14)
The electronic structure of a molecular quantum ring (stacks of 40-unit cyclic porphyrin polymers) is characterised via scanning tunnelling microscopy and scanning tunnelling spectroscopy. Our measurements access the ...
Graphene nanoribbons with hBN passivated edges grown by high-temperature molecular beam epitaxy
(The University of Nottingham, 2023-02-07)
Integration of graphene and hexagonal boron nitride (hBN) in lateral heterostructures has provided a route to broadly engineer the material properties by quantum confinement of electrons or introduction of novel electronic ...
