Organic Field-Effect Transistors—The Breakthrough at Last

After decades of being laboratory curiosities, organic semiconductors catch up with their inorganic counterparts. Ordinarily an excellent insulator, in a field-effect transistor tetracene 1 transfigures into a semiconductor that rivals amorphous silicon at room temperature, a superconductor below 2.5 K, and the first organic light-emitting material that can act as a solid-state injection laser.
