A structural analysis of ordered CsSb films grown on single crystal graphene and silicon carbide substrates
C. Pennington, M. Gaowei, E. M. Echeverria +10
Alkali antimonides are well established as high efficiency, low intrinsic emittance photocathodes for accelerators and photon detectors. However, conventionally grown alkali antimo…
Ab initio study of the crystal and electronic structure of mono- and bi-alkali antimonides: Stability, Goldschmidt-like tolerance factors, and optical properties
J. K. Nangoi, M. Gaowei, A. Galdi +4
Mono- and bi-alkali antimonides, XYSb (X and Y from Group I), are promising for next-generation electron emitters due to their capability of producing high-quality electron bea…
Quantum efficiency enhancement of bialkali photocathodes by an atomically thin layer on substrates
Hisato Yamaguchi, Fangze Liu, Jeffrey DeFazio +15
We report quantum efficiency (QE) enhancements in accelerator technology relevant antimonide photocathodes (K2CsSb) by interfacing them with atomically thin two-dimensional (2D) cr…
Free-standing bialkali photocathodes using atomically thin substrates
Hisato Yamaguchi, Fangze Liu, Jeffrey DeFazio +10
We report successful deposition of high quantum efficiency (QE) bialkali antimonide K2CsSb photocathodes on graphene films. The results pave a pathway towards an ultimate goal of e…
