Abstract

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