Using scanning probe microscopy techniques, at low temperatures and in ultrahigh vacuum,
individual molecules adsorbed on surfaces can be probed with ultrahigh resolution to …

The quest for planar sp2-hybridized carbon allotropes other than graphene, such as
graphenylene and biphenylene networks, has stimulated substantial research efforts …

Abstract Synthetic two-dimensional (2D) materials have no bulk counterparts and typically
exist as single atomic layers due to substrate-stabilized growth. Multilayer formation …

Advances in instrumentation for experimental characterization of materials such as
microscopy and spectroscopy have led to an explosion in information available on materials …

The zigzag-edged triangular graphene molecules (ZTGMs) have been predicted to host
ferromagnetically coupled edge states with the net spin scaling with the molecular size …

Topological band theory predicts that a topological electronic phase transition between two
insulators must proceed via closure of the electronic gap. Here, we use this transition to …

The ability to engineer geometrically well-defined antidots in large triangulene homologues
allows for creating an entire family of triangulene quantum rings (TQRs) with tunable high …

Integration of dissimilar two-dimensional (2D) materials is essential for nanoelectronic
applications. Compared to vertical stacking, covalent lateral stitching requires bottom-up …

Substituting carbon with silicon in organic molecules and materials has long been an
attractive way to modify their electronic structure and properties. Silicon-doped graphene …

The synthesis of polycyclic aromatic hydrocarbons containing various non-benzenoid rings
remains a big challenge facing contemporary organic chemistry despite a considerable …
