Patterning the organic electrodes of all-organic thin film transistors with a simple spray printing technique

The authors have demonstrated the application of spray printing technique for patterning organic electrodes of all-organic transistor on flexible polymeric substrate. Our spray printing technique is a simple, fast, and easy patterning process. The performance of the device obtained with the spray printing technique is shown to be comparable to that of the device with deposited metal electrodes (gold). Thus this spray printing technique provides a method for patterning the electrodes of all-organic transistors.
