Highly Efficient Patterning of Organic Single‐Crystal Transistors from the Solution Phase

Organic single-crystal and polymer FET arrays can be fabricated using a novel solution-based technique. The patterning of the organic semiconductor is achieved by semiconductor solution droplets selectively wetting the transistor electrode pads. The key advantages of the technique are the cleanliness of the patterning, the patterning speed, and the ultrasmall amount of material required.
