Abstract
We report the first experimental evidence of the existence of extended states in one-dimensional random potentials. Our results are obtained by investigating photoconductivity and optical absorption of GaAs/(Al Ga)As disordered superlattices. The experimental results agree with th e numerical and analytical predictions, thus indicating the possibilit y to design narrow bands of extended states at selected energies in di sordered superlattices.
