  • Abstract
    Al0.24Ga0.76N photocathode with 150nm emission layer has been activated by Cs/O. The spectral response of the AlGaN photocathode was measured, the result shown that the response cut-off wavelength was 315nm. The peak value of spectral response in reflection-mode and transmission-mode was 33mA/W and 5.8mA/W respectively.
