Strains strongly affect the properties of low-dimensional materials, such as graphene. By combining in situ, in operando, reflection high-energy electron diffraction experiments with first-principles calculations, we show that large strains, above 2%, are present in graphene during its growth by chemical vapor deposition on Ir(111) and when it is subjected to oxygen etching and ion bombardment. Our results unravel the microscopic relationship between point defects and strains in epitaxial…

Removing Defects: Healing Single Vacancy Defects
During epitaxial graphene growth vacancy defects may be formed in the graphene structure. These defects are undesirable since they affect the electronic properties of the graphene and reduce the
Depressions by stacking faults in nanorippled graphene on metals
A broad variety of defects has been observed in two-dimensional materials. Many of these defects can be created by top-down methods such as electron irradiation or chemical etching, while a few of
What Drives Metal-Surface Step Bunching in Graphene Chemical Vapor Deposition?
It is proved that the SB can occur even in the absence of a compressive strain, is enabled by the rapid diffusion of metal adatoms beneath the graphene and is driven by the release of the bending energy of the graphene overlayer in the vicinity of steps.
Interfacial carbon nanoplatelet formation by ion irradiation of graphene on iridium(111).
These findings shed light on the microscopic mechanisms of defect production in supported 2D materials under ion irradiation and pave the way toward precise control of such systems by ion beam engineering.
Structure of graphene and a surface carbide grown on the (0001) surface of rhenium
Transition metal surfaces catalyse a broad range of thermally-activated reactions involving carbon-containing-species -- from atomic carbon to small hydrocarbons or organic molecules, and polymers.
Single-Layer Graphene as an Effective Mediator of the Metal-Support Interaction.
It is demonstrated that the in-between graphene layer influences both the oxidation state and the morphology of cobalt upon annealing in vacuum, which exhibits remarkable stability upon cobalt deposition and vacuum annealed, while interaction with reactive gases can facilitate the formation of defects.
From Permeation to Cluster Arrays: Graphene on Ir(111) Exposed to Carbon Vapor.
A new type of predominantly sp2-hybridized nanostructured and ultrathin carbon material emerges, which may be useful to encage or stably bind metal in finely dispersed form.
Mutual influence of uniaxial tensile strain and point defect pattern on electronic states in graphene
Abstract The study deals with electronic properties of uniaxially stressed mono- and multi-layer graphene sheets with various kinds of imperfection: point defects modelled as resonant (neutral)
