Planar bridging an atomically precise surface trench with a single molecular wire on an Au(111) surface

Autor: Thupakula, Umamahesh, Bouju, Xavier, Castro-Esteban, Jesús, Dujardin, Erik, Peña, Diego, Joachim, Christian

Publikováno v: Chemical Physics Letters, Elsevier, 2022, 806, pp.140029

In a bridge configuration, a single graphene nanoribbon (GNR) is positioned with a picometer precision over a trench in between two monoatomic steps on an Au(111) surface. This GNR molecular wire adopts a deformed conformation towards the down terrac

Circumventing the Stability Problems of Graphene Nanoribbon Zigzag Edges

Autor: Lawrence, James, Berdonces-Layunta, Alejandro, Edalatmanesh, Shayan, Castro-Esteban, Jesús, Wang, Tao, Mohammed, Mohammed S. G., Vilas-Varela, Manuel, Jelinek, Pavel, Peña4, Diego, de Oteyza, Dimas G.

Carbon nanostructures with zigzag edges exhibit unique properties with exciting potential applications. Such nanostructures are generally synthesized under vacuum because their zigzag edges are unstable under ambient conditions: a barrier that must b

Transferring Axial Molecular Chirality Through a Sequence of On-Surface Reactions

Autor: Merino-Díez, Néstor, Mohammed, Mohammed S. G., Castro-Esteban, Jesús, Colazzo, Luciano, Berdonces-Layunta, Alejandro, Lawrence, James, Pascual, J. Ignacio, de Oteyza, Dimas G., Peña, Diego

Publikováno v: Chemical Science 2020

Fine management of chiral processes on solid surfaces has progressed over the years, yet still faces the need for the controlled and selective production of advanced chiral materials. Here, we report on the use of enantiomerically enriched molecular

Uncovering the Triplet Ground State of Triangular Graphene Nanoflakes Engineered with Atomic Precision on a Metal Surface

Autor: Li, Jingcheng, Sanz, Sofia, Castro-Esteban, Jesus, Vilas-Varela, Manuel, Friedrich, Niklas, Frederiksen, Thomas, Peña, Diego, Pascual, Jose Ignacio

Publikováno v: Phys. Rev. Lett. 124, 177201 (2020)

Graphene can develop large magnetic moments in custom crafted open-shell nanostructures such as triangulene, a triangular piece of graphene with zigzag edges. Current methods of engineering graphene nano-systems on surfaces succeeded in producing ato
