Beyond Silicon

Working with carbon nanotubes, quantum materials, and spintronic devices, our Beyond Silicon researchers are developing technologies that increase processing speed, reduce power consumption, and maintain high performance.

These breakthroughs are reshaping how chips are built and how they function. A major milestone in aligning carbon nanotubes has opened the door to faster, more energy-efficient transistors and flexible electronics. Meanwhile, quantum and spintronic research is enabling new types of memory and computing systems that are faster, more secure, and less power-hungry.

The impact goes far beyond the labs. These innovations support high-performance computing, secure communications, and advanced memory systems. They help industries build smarter tools and systems, and they have real public benefit—from better medical diagnostics to stronger national defense.

UW–Madison engineers use a solution process to deposit aligned arrays of carbon nanotubes onto 1 inch by 1 inch substrates. The researchers used their scalable and rapid deposition process to coat the entire surface of this substrate with aligned carbon nanotubes in less than 5 minutes. The team’s breakthrough is paving the way for carbon nanotube transistors to replace silicon transistors, and is particularly promising for wireless communications technologies.
