Beyond Silicon: Michigan Tech Pioneering Transistors Sans SemiconductorsFor decades, electronic devices have been getting smaller, and smaller, and smaller. It’s now possible -- even routine -- to place millions of transistors on a single silicon chip. But silicon transistors can only get so small. Now, researchers at Michigan Technological University are making transistors out of nanotubes -- which allows much smaller structures.
