back to article Physicists iron out lumps in quantum dots

Continuing to shrink the scale of electronics presents a host of problems, including the way surfaces interact with electrons. At the smallest scale, it's difficult to get a "ballistic" electron to follow a consistent path, something an international team of physicists hopes to solve. In a paper published in Physical Review …
