The unique machine, the first of its kind in North America, is capable of milling in three dimensions with nanometer precision.
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.
Tiny sheets of the semiconductor zinc oxide could have huge implications for the future of a host of electronic and biomedical devices.
