Abstract
Recently, 3-dimensionally laterally-confined semiconductor quantum wells (“quantum dots”) have been realized. These structures are analogous to semiconductor atoms, with energy level separation of order 25 meV, and tunable by the confining potentials. A systematic study reveals a (radius)-1 dependence on the energy separation. The spectra corresponds to resonant tunneling from laterally-confined emitter contact subbands through the discrete 3-dimensionally confined quantum dot states. Momentum non-conservation is observed in these structures.
