Physicists have just created a working transistor out of a tiny phosphorous atom placed within atomic scale electrodes all within a silicon crystal. It’s the precision with which the atom and the other constructs are placed that is key to this breakthrough.
Previously single atom transistors only been achieved by chance or fine tuning multi-atom devices — and when the positioning is off even by ten nanometers it is enough to create operational slow down.
So how did scientists get this to finally work so precisely?
