The electron energy distribution from Au island films shows field emission and hot‐electron emission in two different regions of the applied voltage. The two processes can be determined by their relative energetic position compared with UV photoelectrons and their dependence on the voltage applied. There are field emission in the high‐voltage region (Up > 8 V) following the Fowler‐Nordheim equation and electron excitation at low voltages (Up < 8 V).
