AlGaAs/GaAs superlattice grown by molecular beam epitaxy for its application to semiconductor photocathode

AlGaAs/GaAs superlattice photocathode grown by molecular beam epitaxy: correspondence between room temperature photoluminescence and quantum efficiency

“…At the abstract of the solid-state devices and materials 2020 conference, we reported the molecular beam epitaxy of an AlGaAs/GaAs superlattice structures, investigated their photoluminescence (PL), and the quantum efficiency of photoelectron emissions. 4) The growth of the AlGaAs/GaAs fine-structured superlattices requires a developed epitaxial growth technique. And, their optical quality should have a correlation with the efficiency of the photocathodes.…”
