9 Aug 2019 | Abstract: | The realization of the unusual properties of 2-d materials requires the
formation of large domains of single layer thickness, extending over the
mesoscale. It is found that the formation of ideal graphene on SiC, contrary to
textbook diffraction , is signaled by a strong bell-shaped-component (BSC)
around the (00) and G(10), but not the SiC(10) spots.The BSC is also seen for
graphene on metals, because single layer uniform graphene with large lateral
size can also be grown.It is only seen by electron diffraction and not with
X-ray or He-scattering experiments. Most likely it originates from the spatial
confinement of the graphene electrons within a single layer.This leads to a
large spread in their wavevector, which is transferred through
electron-electron interactions to the elastically scattered electrons to
generate the BSC. | Source: | arXiv, 1908.3506 | Services: | Forum | Review | PDF | Favorites |
