A key step in unlocking the potential for greener, faster, smaller electronic circuitry was taken recently by a group of researchers led by UAlberta physicist Robert Wolkow.

The research team found a way to delete and replace out-of-place atoms that had been preventing new revolutionary circuitry designs from working. This unleashes a new kind of silicon chips for use in common electronic products, such as our phones and computers.

“For the first time, we can unleash the powerful properties inherent to the atomic scale,” explained Wolkow, noting that printing errors on silicon chips are inevitable when working at the atomic scale. “We were making things that were close to perfect but not quite there. Now that we have the ability to make corrections, we can ensure perfect patterns, and that makes the circuits work. It is this new ...

UAlberta physicists upend what is known about northern lights

New model shows mechanism thought to be behind certain classes of northern lights may not even exist.

What scientists thought caused certain classes of northern lights is not what causes certain classes of northern lights. In a landmark study that has toppled what scientists know about the night
