PARADIM users affiliated with Cornell’s Center for Bright Beams, an NSF Science and Technology Center, have developed a novel method to grow single-crystal alkali antimonide photocathodes. The new technique yields materials with electron emission efficiencies up to 10 times greater than previous designs, a breakthrough for electron beam applications including ultrafast electron microscopy and advanced accelerators.
The work highlights the power of PARADIM’s synthesis platforms in enabling next-generation materials for quantum and beam science.
