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 …
Doping also had an "affect" on me at the weekend!
Isn't there a problem with this?
Removing all the dopants is not an option as then it won't be a semiconductor any more, just a plain old silicon insulator.
Re: Isn't there a problem with this?
Haven't read the paper, but perhaps they mean they move the dopants out of the way of the (desired) electron trajectories; whilst leaving them sufficiently nearby so as to leave other properties unchanged.
