摘要
We report the results on polarized electron emission from a new strained InGaAlAs/AlGaAs superlattices with an enlarged band gap, modulation doping and an optimized last GaAs layer. The yield and polarization measurements show that this structure delivers more than 0.1% quantum yield at the maximum of the polarization spectrum, the maximum polarization degree being equal to 80% at room temperature. These values present a 10-fold improvement in the quantum yield over that of the previously designed InAlGaAs-AlGaAs superlattices at the same vacuum conditions.
