Abstract
One or more embodiments relates to a system and method for growing ultrasmooth and high quantum efficiency photocathodes. The method includes exposing a substrate of Si wafer to an alkali source; controlling co-evaporating growth and co-deposition forming a growth including Te; and monitoring a stoichiometry of the growth, forming the photocathodes.
