Figure 4

(a–d) The plots show that the projections of the p-wave induced symmetries in SLG are dependent on the crystal orientation of the underlying PCCO. This is clearest in (d) which illustrates the relationship between the observed DoS on SLG and the plane normal to the underlying PCCO: on flat regions oriented along the [001] crystallographic direction, the DoS corresponds to py-wave or antinodal -wave with a strong tunnelling barrier (red curve in a); rough areas expose a mixture of normal planes oriented between the [001] and [110] crystallographic directions, where the DoS corresponds to py-wave with a moderate tunnelling barrier (green curve in b); the DoS corresponding to the px-wave is projected on the phase oriented along the [110] crystallographic direction (blue curve in c).
