Revolutionary One-Atom-Thick Ribbons Set To Transform Batteries and Solar Cells
Researchers at University College London have developed one-atom-thick ribbons composed of a phosphorus and arsenic alloy. This breakthrough material holds the potential to significantly enhance the performance of various devices including batteries, supercapacitors, and solar cells.
The research team discovered phosphorus nanoribbons in 2019. The “wonder material,” predicted to revolutionize devices ranging from batteries to biomedical sensors, has since been used to increase lithium-ion battery lifetimes and solar cell efficiencies.
However, phosphorus-only materials do not conduct electricity very well, hindering their usage for certain applications.
Enhancements with Arsenic
In the new study, published in the Journal of the American Chemical Society, the researchers created nanoribbons made of phosphorus and tiny amounts of arsenic, which they found were able to conduct electricity at temperatures above -140 C, while retaining the highly useful properties of the phosphorus-only ribbons.
