Asset Details

Description:
STM images of carbon layers grown by deposition of PIC (a–f) and CR (g–i) at different sample temperatures. a,g) Dendritic aggregates observed after growth with PIC and CR at 350 °C. b–c), h) Deposition of PIC and CR at temperatures ranging from 400–450 °C leads to dense layers with progressively larger graphene domains and fewer topographically high features. d–f, i) Deposition of PIC and CR at 550–650 °C) leads to graphene and defective graphene layers with progressively fewer dark trenches. Imaging parameters: a) 330 pA, 22 mV; b) 330 pA, 24 mV; c) 220 pA, 32 mV; d) 330 pA, 24 mV; e) 110 pA, 23 mV; f) 490 pA, 22 mV; g) 210 pA, 29 mV, h) 410 pA, 23 mV; i) 530 pA, 29 mV. For visibility, in images (d,e,g,h) the contrast is folded at step edges.
