Dear Colleagues,

Thin-film photocathodes in typical nano/microscale form are prevalently utilized to provide electron beams of increasingly stringent requirements for interdisciplinary researches and practical applications. The design capabilities of photocathodes in electron sources/devices have become an enabling technology in diverse fields such as light sources and detectors, electron cooling, ultrafast electron diffraction, novel particle accelerators, radiology and radiation oncology, electron beam lithography, etc.

In recent years, research frameworks centering on various cathode materials have been formed and recognized in worldwide cathode communities. Collective research efforts toward novel materials and applications have been made to intercorrelate photocathode/photoemission models, nanosynthesis methods, surface sciences, and diagnostics with comprehensive studies extending from broad fundamental interests in cathode performance (e.g., quantum efficiency, intrinsic emittance, response time, robustness, lifetime, etc.), narrowing down to required beam qualities for specific applications.

This Special Issue (SI) aims to summarize recent advances in nano/microscale thin-film photocathode materials across (but not limited to) the above-stated application fields with a focus on cathode materials and performances for light sources and detectors, novel particle accelerators, and ultrafast electron diffraction. The SI is organized through research papers and review articles. Topics include both experimental and theoretical contributions.
