The Last Gasp For Ga As Chips? Not By A Long Shot

Gallium arsenide (GaAs) has long been the semiconductor material of the future. Proponents insist that silicon will someday run out of gas, and GaAs will then become the choice for tomorrow's ever-faster chips. But each time it seemed that gallium arsenide's day was dawning, silicon found new reserves of speed. So, GaAs is still an also-ran in chips.
