Miniband formation at finite electric fields in a graded-gap superlattice
We have investigated a graded-gap superlattice with differential photocurrent spectroscopy at 77 K. The lowest conduction subband …

Local origin of photocurrent in semiconductor superlattices
To trace the origin of photocurrent (PC) in semiconductor superlatices, we have studied the PC spectra as a function of the applied …

Change in dimensionality of superlattice excitons induced by an electric field
We have observed an electric-field-induced change in the dimensionality of excitons in superlattices, from three to quasi-two …

Interactions between extended and localized states in superlattices
We have observed electric-field-induced interactions between the extended states of a (40 Å)-(15 Å) GaAs-Ga0.65Al0.35As superlattice …

Temperature Dependence of the Electronic Coherence of GaAs-GaAlAs Superlattices
We have shown that the coherence length of electrons in a 55-Å-period GaAs-GaAlAs superlattice does not depend strongly on temperature …
