A FIELD-ELECTRON EMISSION DETERMINATION OF THE WORK FUNCTION OF THE TUNGSTEN (211) PLANE.

Abstract

A value of 6.9 plus or minus 0.5 eV has been measured for the work function of a (211) plane of a thermally-smoothed tungsten field emitter. A retarding-potential analyzer was used to obtain Fowler-Nordheim data and total-energy distributions at room temperature. A family of energy distributions has been employed according to the method of Young in order to take into account the presence of patch fields at the surface of the emitter. This value is larger by 1.5 to 2.0 eV than those determined by other methods. (Author)
