" As devices shrink below the micron regime, a very different and interesting world is unveiled. In a recent paper, the resistance of submicron junctions is shown to behave nonlinearly with current injection.

" A true dynamical calculation at finite temperatures of an impurity diffusing in a crystal is now possible with full quantum mechanical treatment of the electronic system. No phenomenology here! Just sit back and watch a hydrogen atom run around in silicon.
