The Johnsen-Rahbek effect is briefly described and the existing theories of the phenomenon are discussed. A model is derived expressing the attractive force between the contacting materials as a function of the voltage applied across them. The model, which takes into account the presence of surface irregularities, is obtained by an assessment of the effect of field emission on the electrostatic capacitor forces between the contacting surfaces. Good agreement with existing experimental results is obtained.
