Pitt nanoscientists suggest the use of vacuums to overcome the limits of conventional silicon-based semiconductor electronics With the advent of semiconductor transistors–invented in 1947 as a replacement for bulky and inefficient vacuum tubes–has come the consistent demand for faster, more energy-efficient technologies. To fill this need, researchers at the University of Pittsburgh are proposing a new spin on an old method: a switch from the use of silicon electronics back to...

There is a new way to design computer chips and electronic circuitry for extreme environments: make them out of diamond. A team of electrical engineers at Vanderbilt University has developed all the basic components needed to create microelectronic devices out of thin films of nanodiamond. They have created diamond versions of transistors and, most recently, logical gates, which are a key element in computers. "Diamond-based devices have the potential to operate at higher speeds and require...

Call it Nitelite: The newest app for cell phones might be night vision. A University of Florida engineering researcher has crafted a nickel-sized imaging device that uses organic light-emitting diode technology similar to that found in cell phone or laptop screens for night vision. But unlike night vision goggles, which are heavy and expensive, the device is paper-thin, light and inexpensive, making it a possible add-on to cell phone cameras, even eyeglasses, once it is enlarged. "Really,...

Researchers funded by the Air Force Office of Scientific Research (AFOSR) at the University of Michigan invented a new type of magnetron that may be used to defeat enemy electronics.  A magnetron is a type of vacuum tube used as the frequency source in microwave ovens, radar systems and other high-power microwave circuits. According to Dr. Ron Gilgenbach, an AFOSR-sponsored researcher at the University of Michigan, a new class of magnetrons was invented that holds the potential for more...

Anyone who's vacationed in the mountains or lived on a farm knows that it's hard to get good internet access or a strong cell phone signal in a remote area. Communicating across great distances has always been a challenge. So when NASA engineers designed the Lunar Reconnaissance Orbiter (LRO), they knew it would need an extraordinary communications system. Over the next year, the LRO, NASA's diligent robotic scout, will collect more information about the moon's surface and environment than...

Lee De Forest invented the Audion, a forerunner of the triode, which is an amplifying vacuum tube. The grid controls the filament which sends the current from the filament. The Audion can detect radio signals by applying a small amount of power to the grid that can control a larger current from the filament plate. However, De Forest's Audion is distinct from the true vacuum triode since it is not capable of linear amplification. De Forest found that when gas was in a partial vacuum heated...

The Cathode Ray Tube, which has internal or external means to accelerate and deflect electron beams, is a vacuum tube containing an electron gun and a fluorescent screen. The electron beams that are deflected are used to create images in the form of light emitted from the fluorescent screen. The CRT works by using an evacuated glass envelope which is large, deep, heavy, and relatively fragile. Ferdinand Braun is credited with the first CRT in 1897. It can also be known as the Braun tube....
