By Jeff Hecht THE FIRST microchips to reliably combine the performance of gallium arsenide with the cheapness of silicon are being put through their paces by a US chip maker. The technology could help realise the dream of cheap, superfast circuits that communicate via light rather than electric currents. Chip makers would like to move to gallium arsenide (GaAs) because it can be used to build circuits that switch on and off much faster than those on silicon chips. It’s this switching speed that dictates how fast computers run. And unlike standard silicon,
