Abstract

The field and light induced emission of electrons from ITO film into vacuum has been investigated. Under influence of applied voltage, within the interval from -2 kV to 0V, electron emission into vacuum occured. With increasing voltage and under illumination the electron emission grows monotonically. At low voltage (≤ |-500V|) the increase is linear. At higher voltage this dependence is exponential. Upon the internal field and illumination influence, the emission is about twice as much as without illumination. This may be evidence that the electric field initiates electron collisions, which proceed according to the impact ionization mechanism. The emission intensity-electron energy distribution was found to be close to the Gauss probability function. We have also found the Poisson distribution can be used instead of the Gauss one.
