(Color online) Optoelectronic output characteristics of tetracene LETs employing (a) and (b) electrodes. on the left axis and EL on the right axis vs at increasing . . (c) RW as a function of for devices fabricated on and substrates. The correlation coefficient is 0.99 for and 0.94 for . , , and . Deposition flux of the active films: . Nominal thickness: .

FIG. 3.

(Color online) AFM images of tetracene films grown on substrates patterned with (a) and (b) electrodes. The left panels show film morphology in the channel and the right panels show film morphology on the contacts (Au). In the inset of each figure is reported the corresponding line profile at the electrode step. The images were acquired with a Solver Pro AFM (NT-MDT) in semicontact mode using NSG-01 Si cantilevers. Histograms showing the grain size distribution in the channel for tetracene films grown on substrates patterned with (c) and (d) electrodes.
