Dopant-induced intrinsic bistability in a biased nanowire.
Self-consistent calculations of quantum transport through a single donor atom in the semiconductor nanowire show intrinsic bistability of the nonequilibrium electronic state. We attribute this effect to two distinct ion screening mechanisms.
