Journal ArticleDOI
Porous graphenes: two-dimensional polymer synthesis with atomic precision
Marco Bieri,Matthias Treier,Jinming Cai,Kamel Aït-Mansour,Pascal Ruffieux,Oliver Gröning,Pierangelo Gröning,Marcel Kastler,Ralph Rieger,Xinliang Feng,Klaus Müllen,Roman Fasel,Roman Fasel +12 more
TL;DR: By surface-assisted coupling of specifically designed molecular building blocks, the fabrication of regular two-dimensional polyphenylene networks with single-atom wide pores and sub-nanometer periodicity is demonstrated.
Journal ArticleDOI
Controlled synthesis of single-chirality carbon nanotubes

TL;DR: This work converts molecular precursors into ultrashort singly capped ‘armchair’ nanotube seeds using surface-catalysed cyclodehydrogenation on a platinum surface, and elongates these during a subsequent growth phase to produce single-chirality and essentially defect-free SWCNTs with lengths up to a few hundred nanometres.
Journal ArticleDOI
Two-dimensional polymer formation on surfaces: insight into the roles of precursor mobility and reactivity
Marco Bieri,Manh-Thuong Nguyen,Oliver Gröning,Jinming Cai,Matthias Treier,Kamel Aït-Mansour,Pascal Ruffieux,Carlo A. Pignedoli,Daniele Passerone,Marcel Kastler,Klaus Müllen,Roman Fasel +11 more
TL;DR: It is shown that different balances between diffusion and intermolecular coupling determine the observed branched and compact polyphenylene networks on the Cu and Ag surface, respectively, demonstrating that the choice of the substrate plays a crucial role in the formation of two-dimensional polymers.
Journal ArticleDOI
Field emission properties of carbon nanotubes
TL;DR: In this paper, the authors investigated the field emission properties of nanotube thin films deposited by a plasma enhanced chemical vapor deposition process from 2% CH4 in H2 atmosphere.
Journal ArticleDOI
Engineering of robust topological quantum phases in graphene nanoribbons
Oliver Gröning,Shiyong Wang,Shiyong Wang,Xuelin Yao,Carlo A. Pignedoli,Gabriela Borin Barin,Colin Daniels,Andrew Cupo,Vincent Meunier,Xinliang Feng,Akimitsu Narita,Klaus Müllen,Pascal Ruffieux,Roman Fasel,Roman Fasel +14 more
TL;DR: A flexible strategy based on atomically precise graphene nanoribbons to design robust nanomaterials exhibiting the valence electronic structures described by the SSH Hamiltonian is presented and controlled periodic coupling of topological boundary states are demonstrated to create quasi-one-dimensional trivial and non-trivial electronic quantum phases.
