CHAPTER Photocathodes Wei Liu1,2,3, Matt Poelker3, John Smedley4, Romain Ganter5 1Institute of Modern physics, Chinese Academy of Sciences, 509 Nanchang Rd., Lanzhou, 730000, China 2University of Chinese Academy of Sciences,19A Yuquan Rd., Beijing, 100049, China 3Thomas Jefferson National Accelerator facility, 12000 Jefferson Avenue, Newport News, Virginia, 23606, USA 4 Affiliation of John ???? 5Paul Scherrer Institut, 5232 Villigen PSI, Switzerland Abstract Photocathodes were at the of quantum physics development in the early twentieth century and are still used in high technologies devices like night , photomultiplier particle accelerators. The simplest form of photocathode is a metallic surface negatively biased from which electrons are extracted by energetic photons. After a brief description of the photocathode preparation, this chapter will present the latest developments and limitations of metallic and semi-conductor photocathodes.
