- Abstract
This paper discusses the effect of forming gas (93%N2 + 7%H2) plasma treatment for sol-gel methyl-silsesquioxane (MSQ) as a dielectric film towards the grain morphology of a solution processable pentacene. Atomic force microscopy and X-ray diffractometer results confirm that a brief (10 s) plasma treatment for MSQ increases the grain size of pentacene and encourages its growth in thin-film phase. This paper also demonstrates that the presence of large Si(CH3)3 bonds on the MSQ surface are very important to encourage the growth of pentacene’s molecules in thin-film phase. In addition, this paper also suggests that there is no strong relationship between the grain size and ordering of pentacene molecules.
