| Abstract(in English) | We report the influence of X states on the optical properties of type-I GaAs/AlAs semiconductor superlattices. We observed Stark ladder photoluminescence (PL) in some X states originating from X1-Γ2 mixing. The PL line exhibits a linear blue shift corresponding to one half the period of the super-lattice with increasing bias voltage. The PL intensity then becomes maximum when the X1-Γ2 mixing occurs. Carrier sweep-out from the X states is drastically improved by the X1-Γ2 mixing. These results demonstrate that optical properties even in type-I superlattices are seriously affected by the mixing of X states with a higher Γ subband under an electric field. |
