Vacuum Tube Technology Could manufacture Faster Circuits

August 19, 2012 · Print This Article

New obstacles with the limits of electron flow through semiconductors are one of the many problems engineers face as they continue to push for increased speed and ability for electronic devices. But a team of researchers is looking back at the technology of the vacuum tube to develop a means to increase circuit and computational speed.

Once it was invented in the late 1940s, the transistor began to replace the vacuum tube, and

led to an amazing range of uses for solid-state devices and the variety of electronic gadgets we have today. Transistors offered savings in both size and energy. But one of the things that vacuum tubes provided was an obstacle free path for unhindered electron flow through the vacuum. “Electrons traveling inside a semiconductor

device frequently experience collisions or scattering in the solid-state medium.” The problem with vacuum tubes, […]
