Molecular adsorption induces the transformation of rhombohedral- to Bernal-stacking order in trilayer graphene.
The Bernal (ABA)-stacked graphene trilayer is presumed to be thermodynamically more stable than the rhombohedral (ABC) counterpart. However, the thermal transformation from ABC to ABA domains does not occur at a temperature lower than 1,000 °C. Here we report that ABC-stacked trilayers are transformed to ABA-stacked layers after an organic molecule triazine is evaporated onto graphene surfaces ...
متن کاملCORRIGENDUM: Multiple π-bands and Bernal stacking of multilayer graphene on C-face SiC, revealed by nano-Angle Resolved Photoemission
The authors neglected to cite a related study that reports an ARPES experiment indicating the presence of multiple p bands in multilayer graphene on C-face SiC. 1 This is given below as Reference 1. In the present Article, nano-ARPES band mappings of individual graphene grains unambiguously show that multilayer C-face graphene exhibits multiple p-bands.
متن کاملMultiple π-bands and Bernal stacking of multilayer graphene on C-face SiC, revealed by nano-Angle Resolved Photoemission
Only a single linearly dispersing π-band cone, characteristic of monolayer graphene, has so far been observed in Angle Resolved Photoemission (ARPES) experiments on multilayer graphene grown on C-face SiC. A rotational disorder that effectively decouples adjacent layers has been suggested to explain this. However, the coexistence of μm-sized grains of single and multilayer graphene with differe...
متن کاملStacking of Dependency and Phrase Structure Parsers
We investigate the stacking of dependency and phrase structure parsers, i.e. we define features from the output of a phrase structure parser for a dependency parser and vice versa. Our features are based on the original form of the external parses and we also compare this approach to converting phrase structures to dependencies then applying standard stacking on the converted output. The propos...
متن کاملReversible Loss of Bernal Stacking during the Deformation of Few-Layer Graphene in Nanocomposites
The deformation of nanocomposites containing graphene flakes with different numbers of layers has been investigated with the use of Raman spectroscopy. It has been found that there is a shift of the 2D band to lower wavenumber and that the rate of band shift per unit strain tends to decrease as the number of graphene layers increases. It has been demonstrated that band broadening takes place du...
