Self-modulation of photoemission at the picosecond time scale
The pulse response of negative electron affinity GaAs photocathode over a wide range of quantum efficiencies has been measured. Low quantum efficiencies, where an intense excitation is needed, may lead to rapid dynamic change of the transport conditions on a time scale of a few picoseconds. This phenomenon is attribute...
