World's Tiniest Possible Transistor Created Out of a Single Phosphorus Atom
Smallest Transistor A scanning tunneling microscope image of a hydrogenated silicon surface shows a 3-D perspective of a single-atom transistor. The red-shaded regions form the electrical leads to a single phosphorus atom in the center. Martin Fuechsle The smallest transistor ever built - probably the smallest that can ever be built - uses a single phosphorus atom, in a breakthrough that could be one more step on the path toward functional quantum computers. Single atoms have served as transistors in other studies, but this is the first time researchers were...
