    "abstract": "Spin-polarized electron photoemission has been studied for\nGaAs/GaAs$_{1-x}$P$_x$ strained superlattice cathodes grown by gas-source\nmolecular beam epitaxy. The superlattice structural parameters are\nsystematically varied to optimize the photoemission characteristics. The\nheavy-hole and light-hole transitions are reproducibly observed in quantum\nefficiency spectra, enabling direct measurement of the band energies and the\nenergy splitting. Electron-spin polarization as high as 86% with over 1%\nquantum efficiency has been observed.",
