Looking for the next CPU breakthrough…

The folks at MIT have made some serious progress in the search for the replacement material for silicon in transistors.
One of the materials being discussed, according to this ZDNet article, is gallium arsenide, even though there are some kinks to be worked out.
The transistor technology is young, and researchers must work through some challenges. For example, InGaAs can break more often than silicon so manufacturing the transistors in bulk could be difficult. Still, del Alamo expects that a prototype of these InGaAs microdevices will be developed in the next two years.
This is something to keep our eyes on for sure.
