Abstract
A dispersion relation epsilon(q) is derived for electrons in a planar superlattice constructed in the form of a quantum well that is coupled by tunneling with a periodic array of parallel strip-shaped quantum w ires. A narrow miniband inside of the substantially wider gap is demon strated for special resonance conditions. Since the obtained spectra a re very sensitive to correlation of different array parameters they ca n be tuned and detuned easily. (C) 1998 Academic Press Limited.
