“…We obtained similar findings in preliminary experiments on Ne + -irradiated graphene on Ir(100) and Ar + -irradiated graphene on Ni(111), the latter observation having been recently confirmed by Späth et al. 43 Finally, we note that our study fosters the investigation of Van der Waals solids under extreme pressure and high temperatures. Indeed, rather than using molecular beams to obtain condensation, our method exploits ripening of Ar implanted under graphene, the cluster size being controlled by a simple annealing process.…”

Nanobubbles at GPa Pressure under Graphene

We provide direct evidence that irradiation of a graphene membrane on Ir with low-energy Ar ions induces formation of solid noble-gas nanobubbles. Their size can be controlled by thermal treatment, reaching tens of nanometers laterally and height of 1.5 nm upon annealing at 1080 °C. Ab initio calculations show that Ar nanobubbles are subject to pressures reaching tens of GPa, their formation being driven by minimization of the energy cost of film distortion and loss of adhesion.

“…3(a)), which is consistent with the previously published results [20]. (The small bump at 283.3±0.1 eV in the C 1s spectrum for gr/Ni (111) is due to the small fraction of the Ni 2 C phase which is rarely avoided during formation of graphene on a Ni(111) single crystal [30,31].) For both systems, the emission line for Ni 2p represents the spin-orbit split doublet at 852.6 ± 0.1 eV and 869.9 ± 0.1 eV as well as the correlation satellite peaks which are located 6 eV below every main emission line.…”

Near-ambient pressure XPS and STM experiments are performed to study the intercalation of oxygen and nitrogen at different partial gas pressures and different temperatures in the graphene/Ni/Ir(111) system of different morphologies. We performed detailed experiments on the investigation of the chemical state and topography of graphene, before and after gas intercalation, depending on the amount of pre-intercalated Ni in graphene/Ir(111). It is found that only oxygen can be intercalated under graphene in all considered cases, indicating the role of the intra-molecular bonding strength and possibility of gas molecules dissociation on different metallic surfaces on the principal possibility and on the mechanism of intercalation of different species under graphene. This document is the unedited author's version of a Submitted Work that was subsequently accepted for publication in J. Phys.

“…The fact that we observe standalone h-BN blisters at high temperatures is intimately linked to the thermal decomposition of h-BN on Ir(111). Standalone blisters, though not triangular, were also observed for Gr on Ni(111) by Späth et al [44] and Larciprete et al [45] under conditions where the Gr dissolves into the Ni bulk. The standalone blisters emerge due to the slower decay rate of the 2D layer separated by a gas cushion from the substrate.…”

“…For blisters formed as a consequence of noble gas irradiation of Gr, it has been proposed several times that these blisters are pressurized [42][43][44][45]. In fact, Zamborlini et al [43] and Larciprete et al [45] even proposed solid Ar in Gr blisters on a metal substrate, when at room temperature.…”

“…In the past few years, ion-induced damage and annealing of Gr on a metal substrate has been intensely investigated: trapping of single noble gas ions under Gr on Ru(0001) [38]; formation of highly pressurized gas blisters under Gr on Pt(111) [39], Ir(111) [40][41][42], Ir(100) [43], and Ni(111) [44,45] upon annealing subsequent to noble gas implantation, damage evolution with ion energy [46]; formation of a regular arrangement of vacancy clusters with moiré periodicity (nanomesh) [47]; interface channeling [47]; and sputter protection of the substrate through a Gr cover [48]. In these studies, room-temperature irradiated Gr demonstrated a remarkable ability to self-repair upon annealing, which one might relate to the flexible bond reorganization in this material.…”

Annealing of ion-irradiated hexagonal boron nitride on Ir(111)

Annealing of a monolayer of hexagonal boron nitride destroyed by Xe ion irradiation gives rise to rich structural phenomena investigated here through a combination of scanning tunneling microscopy, low-energy electron diffraction, x-ray photoelectron spectroscopy, and density functional theory calculations. We find selective pinning of vacancy clusters at a single specific location within the moiré formed by hexagonal boron nitride (h-BN) and the Ir substrate, crystalline Xe at room temperature of monolayer and bilayer thickness sealed inside h-BN blisters, standalone blisters only bound to the metal at temperatures where boron nitride on Ir (111) decomposes, and finally a pronounced threefold symmetry of all morphological features due to the preferential formation of boron-terminated zigzag edges that firmly bind to the substrate. The investigations give clear insight into the relevance of the substrate for the damage creation and annealing in a two-dimensional layer material.
