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…
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…
Observation of the Ferromagnetic Kondo Effect
Elia Turco, Nils Krane, Hongyan Chen +5
The quest for quantum ground states beyond the conventional Fermi-liquid paradigm remains a central challenge in many-body physics. The ferromagnetic Kondo effect represents a part…
Optimized Synthesis and Device Integration of Long 17-Atom-Wide Armchair Graphene Nanoribbons
Jeong Ha Hwang, Nicolò Bassi, Mayada Fadel +15
Seventeen-carbon-atom-wide armchair graphene nanoribbons (17-AGNRs) are promising candidates for high-performance electronic devices due to their narrow electronic bandgap. Atomic…
Atomic-scale imaging of graphene nanoribbons on graphene after polymer-free substrate transfer
Amogh Kinikar, Feifei Xiang, Lucia Palomino Ruiz +12
On-surface synthesis enables the fabrication of atomically precise graphene nanoribbons (GNRs) with properties defined by their shape and edge topology. While this bottom-up approa…
