Description
Inspired by the progress of surface plasmon research and the rapid development of nanotechnology, we embarked on an endeavor aiming to improve the GaAs-based photocathode performance by patterning semiconductor wafer surfaces with pillar arrays on the scale of hundreds of nanometers. Over the past a few years, extensive research effort involving both simulation and experimental studies have been made, leading to the demonstration of some important underlying physical mechanisms such as Mie-resonance at different laser wavelengths and strong quantum efficiency enhancement over their peers with conventional flat surfaces. In this report, we present an overview of our research activities including previous work, current status, and the near future plan about an on-going effort to test newly designed nanostructured photocathodes in a high voltage electron gun.
