Abstract

Electronic structures in various coupled quantum box array systems including quantum-wire superlattices and planar superlattices are examined. The optimal choice of coupling and periodicity in such systems results in miniband structures with medium width Eb and wide energy gap Eg and is found to provide a novel method to substantially reduce the optical phonon scattering of electrons in semiconductors. Feasibility and significances of this approach are discussed.
