We report on the effects of field-induced -X resonances on carrier transport and optical properties of GaAs/AlAs type-I short-period superlattices (SLs). We have observed an anomalously delayed photocurrent and 2-hh1 photoluminescence originating from X1-2 mixing. These observations clearly suggest
The effects of mixing between the \(\Gamma\) and \(X\) valleys of the conduction band on the binding energy of a shallow donor in a thin type I AlAs/GaAs quantum well are investigated. The multivalley effective mass equations are solved variationally, with a separable hydrogen-like trial function. T
