• substrate, using synchrotron two-dimensional grazing incidence X-ray diffraction (2D-GIXRD). We show that although graphene induces the face-on stacking of monoclinic domains, the underlying SiO2 substrate can still cause edge-on triclinic orientations as well. We also present the electrical current mapping
