Transparent chips are the way to seeing things better

Reversed logic

Boffins have emerged from their smoke filled labs with transparent thin-film organic semiconductors that could become the foundation for cheap, high-performance displays. Two university research teams have worked together to produce the world's fastest thin-film organic transistors, proving that this experimental technology has the potential to achieve the performance needed for high-resolution television screens and similar electronic devices.



At the moment the high tech method is to drop a special solution, containing carbon-rich molecules and a complementary plastic, onto a spinning platter made of glass. The spinning action deposits a thin coating of the materials over the platter. The boffins worked out that if they spun the platter faster and coated a tiny portion of the spinning surface, equivalent to the size of a postage stamp they could put a denser concentration of the organic molecules into a more regular alignment. The result was a great improvement in carrier mobility, which measures how quickly electrical charges travel through the transistor.
