System Bits: April 24


Some superconductors carry spin currents A few years ago, researchers from the University of Cambridge showed that it was possible to create electron pairs in which the spins are aligned: up-up or down-down. The spin current can be carried by up-up and down-down pairs moving in opposite directions with a net charge current of zero, and the ability to create such a pure spin super-current is an... » read more

Bigger, Brighter TVs


The flat panel display (FPD) industry is undergoing a renaissance, with suppliers rolling out a dizzying array of new, high-resolution technologies for mobile devices, computers and TVs. But despite being in the eye of the innovation storm, FPD equipment makers remain cautious—and for good reason. There are a slew of new LCD fabs being built today, mostly in China. This, in turn, is promp... » read more
