Steady-state longitudinal conductivity of an electron boundary layer

An analytic solution is obtained for the problem of electron motion in an e lectron boundary layer along the surface of a conductor in a static electri c field. Calculations are made of the longitudinal conductivity near the su rface in the limit of weak and strong Coulomb nonideality of the layer elec trons. It is shown that under certain conditions the boundary conductivity may greatly exceed the conductivity in the bulk of the conductor. (C) 1999 American Institute of Physics. [S1063-7842(99)01606-2].
