Ultra-high vacuum Raman platform for in situ characterization of graphene nanoribbons
Jeong Ha Hwang, Amogh Kinikar, Lukas Rotach +9
Atomically precise graphene nanoribbons (GNRs) exhibit tunable electronic and magnetic properties governed by edge topology and finite-size effects, which make them versatile platf…
One-dimensional carbon nanostructures with periodic graphitic nitrogen substitution
Nicolò Bassi, Shantanu Mishra, Zheng Zhang +8
Heteroatom substitution is a powerful route to tune the chemical and electronic properties of carbon nanomaterials. In particular, replacement of an sp2 hybridized carbon atom in t…
Learning Inhomogeneous Heisenberg Hamiltonians in Nanographene Spin Chains
Greta Lupi, Saketh Ravuri, Chenxiao Zhao +9
Inferring microscopic Hamiltonians from experimental data is a central challenge in quantum materials and quantum simulation. In low-dimensional spin systems, exchange interactions…
Step-Edge Passivation and Quantitative Raman Mapping of Transfer Quality in Aligned Graphene Nanoribbons
Dominik Lüthi, Rimah Darawish, Klaus Müllen +2
The transfer of aligned graphene nanoribbons from metallic growth surfaces to device-compatible platforms remains a central bottleneck for nanoribbon electronics. Here, we investig…
Interfacial Coupling and Sparse Intercalation of 7-Atom-Wide Armchair Graphene Nanoribbons by N-Heterocyclic Carbene Monolayers
Dominik Lüthi, Lin Yang, Xiuling Yu +5
Graphene nanoribbons (GNRs) synthesized on metal substrates experience electronic coupling and screening from the underlying surface, which, although often weak, can modify their o…
Engineering Ferrimagnetic Interactions in Molecular Quantum Systems
Elia Turco, Fupeng Wu, Annika Bernhardt +6
Achieving long-range ferrimagnetic order in purely organic systems remains a major challenge in molecular magnetism. Here we report the synthesis and characterization of heterospin…
