The two-dimensional material has a number of remarkable properties.
Some of the most famous scientific discoveries happened by accident. From Teflon and the microwave oven to penicillin, scientists trying to solve a problem sometimes find unexpected things. This is exactly how we created phosphorene nanoribbons—a material made from one of the universe’s basic building blocks, but that has the potential to revolutionize a wide range of technologies.
Transformative potentialMore than 100 scientific papers predicted the transformative potential of these nanoribbons, should it be possible to create them, across a range of technologies—some as many as five years prior to the publishing of our discovery in Nature. The field of electronics may also be thankful for nanoribbons. Moore’s law observes that computer processing power doubles every two years, but this rate is in danger of slowing down as the physical limits of materials are being fast approached. Using ‘2D’ materials like ours could redefine these limits, allowing us to make ever-smaller and faster devices.
The technology could unlock the potential of hydrogen as an efficient and low-carbon fuel. The gas is abundantly available in water and only produces oxygen as a byproduct when extracted. However, finding a way to do this cheaply has thus far eluded scientists. Water molecules can be split through a process called photocatalysis, but the method requires a material that absorbs lots of light, and whose energy properties match up well with water.
