A simple surface treatment technique developed by researchers at the National Institute of Standards and Technology (NIST), Penn State and the University of Kentucky may offer a low-cost way to mass produce large arrays of organic electronic transistors on polymer sheets for a wide range of applications, including flexible displays, “intelligent paper” and flexible sheets of biosensor arrays for field diagnostics.
The researchers found that a chemical pretreatment of electrical contacts can induce self-assembly of molecular crystals to improve the performance of organic semiconductor devices and provide electrical isolation between devices.
