Abstract
Compositions that contain an organic semiconductor dissolved in a solvent mixture are described. More specifically, the solvent mixture includes an alkane having 9 to 16 carbon atoms in an amount equal to 1 to 20 weight percent and an aromatic compound in an amount equal to 80 to 99 weight percent. The semiconductor material is dissolved in the solvent mixture in an amount equal to at least 0.1 weight percent based on a total weight of the composition. Methods of making a semiconductor device using the compositions to form a semiconductor layer are also described.
