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…
Active bialkali photocathodes on free-standing graphene substrates
Hisato Yamaguchi, Fangze Liu, Jeffrey DeFazio +10
The hexagonal structure of graphene gives rise to the property of gas impermeability, motivating its investigation for a new application: protection of semiconductor photocathodes…
High quantum efficiency S-20 photocathodes in photon counting detectors
Dmitry A. Orlov, Jeff DeFazio, Serge Duarte Pinto +2
Based on conventional S-20 processes, a new series of high quantum efficiency (QE) photocathodes has been developed that can be specifically tuned for use in the ultraviolet, blue…
