Scholarcy highlights

  • Homogeneous large-area graphene monolayers were successfully prepared ex situ on 6H-SiC(0001)
  • Different results are observed from the ex situ graphene layers of different thicknesses, which are proposed as a guideline for determining graphene growth
  • Recorded C1s spectra consisted of three components: bulk SiC, graphene, and interface, the latter being a 63 layer
  • A PEEM image obtained using the Si2p level and collected at a photon energy of 130 eV
