Alkali antimonides have a long history as visible-light-sensitive photocathodes. This work
focuses on the process of fabrication of the bi-alkali photocathodes,
K2CsSb. In-situ synchrotron x-ray diffraction and
photoresponse measurements were used to monitor phase evolution during sequential
on Si(100) substrates. The amorphous-to-crystalline transition for the initial
layer was observed at a film thickness of 40 Å . The antimony crystalline
dissolved upon potassiumdeposition,
eventually recrystallizing upon further deposition into K-Sb crystalline modifications. This
transition, as well as the conversion of potassium antimonide to K2CsSb upon cesium
deposition, is correlated with changes in the quantum
