"At this week’s IEEE International Electron Devices Meeting (IEDM) in San Francisco, CA, USA, the Massachusetts Institute of Technology (MIT) presented results on InGaAs-based high-electron mobility transistors (HEMTs) with thin InAlAs barrier layers that could succeed silicon in logic chips.

The increase in performance of CMOS-based ICs with shrinking of the constituent MOSFET transistors is expected to reach a limit for silicon within the next 10-15 years. “Unless we do something very radical pretty soon, the microelectronics revolution that has enriched our lives in so many different ways might come to a screeching halt,” says professor Jesus del Alamo, a member of MIT's Microsystems Technology Laboratories."
