Electrons speed up in coated nanostructures

Physicists and electrical engineers at the University of Notre Dame in the US have proposed a way to speed up the motion of electrons inside semiconductor nanostructures by simply coating the materials with insulators. If realized experimentally, the technique – which works by reducing scattering from impurities that normally slow down electron speed – might be used to increase charge transport in nanoscale devices, such as high-speed transistors.
