Abstract
The formation of high-quality thin films of pentacene is important in electronic applications. We show here that laser ablation, a technique widely used to deposit a variety of inorganic materials, can also be employed for forming thin oligomeric films. Pentacene films produced by the evaporation of a solid target with a pulsed ultraviolet laser are comparable to those produced via thermal evaporation. The composition of the ablation plume suggests that deposition proceeds by way of a laser-induced evaporation followed by condensation on a nearby surface.Laser depositedfilms are single-phase material with interlamella spacing characteristic of thin-filmstructures. The optical properties, field effect mobilities, and surface morphology of laser deposited pentacene films as compared to those produced via thermal evaporation are discussed.This publication has 25 references indexed in Scilit:
