Hierarchical On-Surface Synthesis of Deterministic Graphene Nanoribbon Heterojunctions
Christopher Bronner, Rebecca A. Durr, Daniel J. Rizzo +8
Bottom-up graphene nanoribbon (GNR) heterojunctions are nanoscale strips of graphene whose electronic structure abruptly changes across a covalently bonded interface. Their rationa…
Spatially resolving density-dependent screening around a single charged atom in graphene
Dillon Wong, Fabiano Corsetti, Yang Wang +8
Electrons in two-dimensional graphene sheets behave as interacting chiral Dirac fermions and have unique screening properties due to their symmetry and reduced dimensionality. By u…
Iodine versus Bromine Functionalization for Bottom-Up Graphene Nanoribbon Growth: Role of Diffusion
Christopher Bronner, Tomas Marangoni, Daniel J. Rizzo +4
Deterministic bottom-up approaches for synthesizing atomically well-defined graphene nanoribbons (GNRs) largely rely on the surface-catalyzed activation of selected labile bonds in…
Realization of Quantum Spin Hall State in Monolayer 1T'-WTe2
Shujie Tang, Chaofan Zhang, Dillon Wong +23
A quantum spin Hall (QSH) insulator is a novel two-dimensional quantum state of matter that features quantized Hall conductance in the absence of magnetic field, resulting from top…
Imaging structural transitions in organometallic molecules on Ag(100) for solar thermal energy storage
Jongweon Cho, Ivan V. Pechenezhskiy, Luis Berbil-Bautista +3
The use of opto-thermal molecular energy storage at the nanoscale creates new opportunities for powering future microdevices with flexible synthetic tailorability. Practical applic…
