The idea of a CPU running from a AAA battery is still a few years away, but Dae-Hyun Kim, a post-doctoral associate of MIT professor Jesus del Alamo, intends to present working components at the IEEE International Electron Devices Meeting next week.
They’re frailer than silicon, but InGaAs technology works, & a couple of years’ research should overcome any deficiencies. Professor del Alamo expects real devices to hit the streets within 10 years, pretty much just in time for silicon to stonewall in performance & extensbility terms.
The transistors are prepared in the US, but the “high quality of the semiconductor material”, itself prepared in Singapore, contributed to the transistors’ performance. Existing devices push 2.5x as much current as silicon.
