Abstract
We review a new molecular beam epitaxy (MBE) technique we call cleaved edge overgrowth (CEO), which makes possible fabrication of quantum wi res or other lower dimensional quantum structures with atomic precisio n. CEO is accomplished by performing two separate MBE overgrowths sepa rated by an in situ cleave of the substrate sample. We review our deve lopment of this novel method and give several examples of new structur es recently fabricated using it.
