Аннотация:We report an explicit experimental observation of photostimulated electron field emission from
diamond. The electron emission properties of monocrystalline diamond needles were investigated
in the dark and under illumination by nanosecond laser pulses. A prominent increase in the electron
emission current was detected under illumination by light with photon energies above 5.0 eV. The
linear dependence of the photoinduced emission current on the light intensity was observed in the
spectral range of 5.0 to 5.9 eV, while its field dependence demonstrated saturation behavior. The
remarkable feature of the observed phenomenon was the fact that illuminated and field emission
areas of the diamond needles were spatially separated by about 100 um in the used experimental
setup. Possible mechanisms for the observed effects are discussed.
