A chemistry professor has come up with a more sustainable way to make silicon at much lower temperatures for the kind of advanced batteries used in electronics such as phones, cameras and laptop computers.
Solar charging and electrical discharging, according to a UW researcher, can be repeated for many cycles with little efficiency loss.
Computer chip makers continuously strive to pack more transistors in less space, yet as the size of those transistors approaches the atomic scale, there are physical limits on how small they are able to make the patterns for the circuitry.
For decades, scientists have tried to harness the unique properties of carbon nanotubes to create high-performance electronics that are faster or consume less power. Now, for the first time, University of Wisconsin–Madison materials engineers have created carbon nanotube transistors that outperform state-of-the-art silicon transistors.
