摘要：

We report on photocurrent spectra of quasiperiodic superlattices which are greatly modified when an electric field is applied along the growth axis. We explain this behavior with a simple tight-binding model including only the superlattices sequences on which the different electronic states are peaked at zero electric field thus confirming the wavefunction "localization" of critical states. © 1990.
