Researchers have used nanotechnology to create transparent transistors and circuits, a step that promises a broad range of applications, from e-paper and flexible colour screens for consumer electronics to "smart cards" and "heads-up" displays in auto windshields. The transistors are made of single "nanowires," or tiny cylindrical structures that were assembled on glass or thin films of flexible plastic.rnThe nanowires themselves are transparent, the contacts put on them are transparent and the glass or plastic substrate is transparent, according to a researcher at Purdue University's Birck Nanotechnology Centre. Other researchers had previously created nanowire transistors, but the metal electrodes in the transistors were non-transparent, which made the overall structure opaque.
