6P desorption experiment: (a) Set of transfer curves of a device initially covered with ~4 ML of 6P (Fig. 2(d–f)), in high vacuum before and after desorption of 6P, and in air after desorption of 6P. (b) Current through the device during annealing (solid line) and the corresponding T D (dashed line). (c) Enlarged initial 500 s of (b) showing the desorption temperature for the 6P thin film on graphene. (d) AFM topography of the device prior to desorption experiment, z scale 60 nm. (e,f) Enlarged AFM images of a graphene/SiO2 edge (marked by a square in (d)) before and after annealing (z scale 30 nm).
