Researchers at Duke University have created transistors with three carbon-based inks. The all-carbon thin-film transistors were made using crystalline nanocellulose as a dielectric, carbon nanotubes as a semiconductor, graphene as a conductor and paper as a substrate. This type of component could assist in addressing the environmental problem of accumulation of electronics that are non-recyclable.
“Silicon-based computer components are probably never going away and we don’t expect easily recyclable electronics like ours to replace the technology and devices that are already widely used,” said Professor Aaron Franklin, an electrical engineer at Duke University. “But we hope that by creating new, fully recyclable, easily printed electronics and showing what they can do, that they might become widely used in future applications.”
