Tuning the alignment of pentacene on copper substrate by annealing-assistant surface functionalization |
AFM images of pentacene on post-anneal treated LPC substrates. The annealing duration time (t) is 3 min (a), 10 min (b), and 25 min (c). The nominated thickness of pentacene is 3 nm for all cases shown in this figure. The deposition condition of pentacene is the same as shown in other figures. |
