Abstract
Organic semiconductor material can be patterned from a solution onto a substrate by selectively wetting the substrate with the solution while applying a mechanical disturbance (such as stirring the solution while the substrate is immersed, or wiping the solution on the substrate). The organic semiconductor material can then be precipitated out of the solution, for example to bridge gaps between source and drain electrodes to form transistor devices. In some embodiments, the solution containing the organic semiconductor material can be mixed in an immiscible host liquid. This can allow the use of higher concentration solutions while also using less of the organic semiconductor material.
