Core shift controls grain boundary energy scaling in Cu and Al
Xiaopu Zhang, John J. Boland
Grain boundary energies in different elements are correlated. The proportional scaling constants relating the energies of crystallography-equivalent boundaries in any two f.c.c. el…
Universal preference for low energy core-shifted grain boundaries at the surfaces of fcc metals
Xiaopu Zhang, John J. Boland
Grain boundaries with [111] tilt axes are common in polycrystalline face centered cubic metals. For copper (111) films, emergent grain boundaries close to surface have tilt axes th…
Wedge disclination description of emergent core-shifted grain boundaries at free surfaces
Xiaopu Zhang, Ipen Demirel, John J. Boland
Emergent grain boundaries at free surface control material properties such as nanomaterial strength, catalysis, and corrosion. Recently the restructuring of emergent boundaries on…
Neuromorphic MoS2 memtransistors fabricated by localised helium ion beam irradiation
Jakub Jadwiszczak, Darragh Keane, Pierce Maguire +12
Two-dimensional layered semiconductors have recently emerged as attractive building blocks for next-generation low-power non-volatile memories. However, challenges remain in the co…
Emergence of Winner-takes-all Connectivity Paths in Random Nanowire Networks
Hugh G. Manning, Fabio Niosi, Claudia Gomes da Rocha +8
Nanowire networks are promising memristive architectures for neuromorphic applications due to their connectivity and neurosynaptic-like behaviours. Here, we demonstrate a self-simi…
Oxide-mediated self-limiting recovery of field effect mobility in plasma-treated MoS
Jakub Jadwiszczak, Colin O'Callaghan, Yangbo Zhou +14
Precise tunability of electronic properties of 2D nanomaterials is a key goal of current research in this field of materials science. Chemical modification of layered transition me…
