Tiny, flexible 2D phosphorus nanoribbons could usher in a new generation of electronics and battery tech.
The nanoribbons were created by accident when researchers at the University College London attempted to make sheets of phosphorene and produced ribbons instead. Made up of a mixture of black phosphorus mixed with lithium ion and then dissolved in liquid ammonia, the ribbons are one atomic layer thick, 4 to 50 nanometers wide and up to 75 µm long. They are also extremely flat and flexible, and could be tuned for specific applications—such as fast charging batteries with twice the capacity, wearable electronics and even waste heat harvesters.
