The energy distributions of electron emission from a Schottky emitter have been studied at tip temperatures from 1450K to 1800K and angular current densities from 0.1 uA/sr to 240uA/sr. We have observed broadening of the energy distribution, with increase of angular current density and decrease of tip temperature, from 0.4 eV to 1.32 eV resulting from electron tunneling and electron-electron interaction. Good agreement between the experimetnal results and predictions from Monte Carlo simulation of the emission process is observed.
