- Abstract
- The electrical performance of a thin film in an organic thin film transistor depends on the film morphology. A mixed solvent system was demonstrated to provide a useful method for controlling the morphologies of organic semiconductor layers in organic thin film transistor. To overcome the limitations on solvent properties, control over the morphology of a 2-(6-((2-ethylhexyl)oxy)naphthalen-2-yl)anthracene film using a tetrahydrofuran/chloroform mixed system (with ratio of 1:5 w/w). Here, in an effort to achieve improved the device electrical performance properties for use in organic thin film transistors, we have examined a mixed solvent system that is suitable for the fabrication of organic semiconductors.
