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…
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…
Conformational tuning of magnetic interactions in coupled nanographenes
Gonçalo Catarina, Elia Turco, Nils Krane +6
Phenalenyl (CH) is an open-shell spin- nanographene. Using scanning tunneling microscopy (STM) inelastic electron tunneling spectroscopy (IETS), covalently-bonded p…
Layer-Dependent Charge State Lifetime of Single Se Vacancies in WSe
Laric Bobzien, Jonas Allerbeck, Nils Krane +7
Defect engineering in two-dimensional semiconductors has been exploited to tune the optoelectronic properties and introduce new quantum states in the band gap. Chalcogen vacancies…
Synthesis and characterization of super-nonazethrene
Elia Turco, Shantanu Mishra, Jason Melidonie +6
Beginning with the early work of Clar et al. in 1955, zethrenes and their laterally-extended homologues, super-zethrenes, have been intensively studied in the solution phase, and a…
Observation of fractional edge excitations in nanographene spin chains
Shantanu Mishra, Goncalo Catarina, Fupeng Wu +9
Fractionalization is a phenomenon in which strong interactions in a quantum system drive the emergence of excitations with quantum numbers that are absent in the building blocks. O…
