Super flexible semiconductors for printed displays

18.08.2023 - New composite semiconductor is made up of a water-insoluble polymer and indium oxide.

Traditional semi­conductor devices used in display industries are either made of amorphous silicon or amorphous oxides, both of which are not flexible and strain tolerant at all. Adding polymers to the oxide semi­conductors may increase their flexibility, but there is a limit to how much can be added without compromising the semiconductor’s performance. Now, the researchers have found a way to fabricate a composite containing a significant amount of polymer – up to 40 % of the material weight – using a solution-process technique, speci­fically inkjet printing. In contrast, previous studies have reported only up to 1-2 % polymer addition. Interestingly, the approach enabled the semi­conducting properties of the oxide semiconductor to remain unaltered with the polymer addition. The added large quantity of polymer also made the composite semi­conductor highly flexible and foldable without deteriorating its performance.

He adds that in the future, such printed semi­conductors can be used to fabricate fully printed and flexible television screens, wearables, and large electronic billboards alongside printed organic light emitting diode display front-ends. These printed semi­conductors will be low-cost and easy to manufacture, which could potentially revolutionize the display industry.
