KIT researchers develop single atom transistor

I've only had one warning from the Mods so far...

You're not trying hard enough!!

I followed the link in the article.

... “By an electric control pulse, we position a single silver atom into this gap and close the circuit,” Professor Thomas Schimmel explains. “When the silver atom is removed again, the circuit is interrupted.”

There's so much missing from that press release - Where exactly is the silver atom when it's not in the gap? Does another "control pulse" open the circuit again or are they having to manually reset it?
Switching speeds are critical to the usefulness of a transistor but I suppose that's almost irrelevant at such an early stage in the research.

Followed a link? In an article? How dare you do such a thing.

Uninformed conjecture is how the internet functions. How dare you challenge that?
