(Nanowerk News) Over the past 70 years, the number of transistors on a chip has doubled approximately every two years – according to Moore’s Law, which is still valid today. The circuits have become ...

The first transistors were point contact devices, not far from the cats-whiskers of early radio receivers. They were fragile and expensive, and their performance was not very high. The transistor ...

(Nanowerk News) The foundation of many, many modern electronic devices – including computers, smart phones, and televisions – is the silicon transistor. However, the shrinking of consumer electronics ...

In the beginning, there was the point-contact transistor. This was the very first transistor ever made, built by Walter Brattain with the help of John Bardeen. It was made of two gold foil contacts ...

Normally, computer chips consist of electronic components that always do the same thing. In the future, however, more flexibility will be possible: New types of adaptive transistors can be dynamically ...

AF114 germanium transistors and related ones like the AF115 through AF117 were quite popular during the 1960s, but they quickly developed a reputation for failure. This is due to what should have made ...

A research team from IBM and the Georgia Institute of Technology has demonstrated the first silicon-germanium transistor able to operate at frequencies above 500 GHz. Though the record performance was ...

Sometimes, a technique or technology that initiates a radical or dramatic advance is soon itself overtaken by a variation or improvement on that initial innovation, with an excellent example being ...

Scientists at Forschungszentrum Jülich have fabricated a new type of transistor from a germanium–tin alloy that has several advantages over conventional switching elements. Charge carriers can move ...
