Tuning the alignment of pentacene on copper substrate by annealing-assistant surface functionalization |
AFM images of bare LPC and pentacene films on LPC substrates: (a) bare LPC, (b) pentacene of 0.4 ML on LPC, (c) pentacene of 1.0 ML on LPC substrate. The curves shown at the bottom of each panel are the height profiles taken from the regions marked with the solid lines shown in panels (a)–(c). |
