An unbelievable speed of 500GHz!!!
When cooled to -268.5C, using liquid helium, it is able to perform a speed of 500 GHz! Even at room temperature they can be running at 350 GHz.
Other than standard silicon chips, these chips are manufactured using Si-Ge technology.
Germanium is already added to the silicon chips used in mobile phones to make them operate more efficiently.
Adding the element allows chips to run faster and use less power. Importantly, they can also be fabricated using existing silicon techniques.
The team believes it is possible to make chips run at 1,000 Ghz, or one Terahertz, at room temperature.
OK. After some digging. This is a transistor which can be switched at 500GHz. It could probably be used in RF usage. The largest advantage is it uses SiGe. This technology is relative cheaper than others in high frequency transistor.
