A team of UW-Madison materials scientists have developed a method for aligning atomically thin rolls of graphene – called carbon nanotubes – to enable next-generation electronics. The well-aligned, high-density carbon nanotubes act like tiny semiconducting wires that can significantly outperform silicon. Semiconductors, which underpin all of modern electronics from our cars to the microprocessors in our phones, have relied on inorganic materials like silicon for more than 50 years. As industry maxes out the performance of such devices, carbon nanotubes are poised to take electronics to the next level.
