Abstract :
Sharp metal tips as field emitters are well-known and established electron sources. A DC-electric field leads to a continuous electron tunnel current out of the high-energy tail of the electron thermal distribution. In contrast in this paper, the authors present a project where electrons are emitted due to the high electric field delivered by ultrashort laser pulses.
