Transistor built on vacuum tube principles may reach frequencies that silicon cannot. There's a chance that vacuum tube technology could make its way back into computers—albeit without the vacuum—thanks to NASA research that has put together nanoscale "vacuum channel" transistors that can switch at more than 400GHz.
