Effect on impurities of one-dimensional hopping conductivity: Saturation of current
Journal Article
·
· Phys. Rev., B; (United States)
Hopping conductivity is considered in a one-dimensional (1D) system with a finite density of impurities which present a finite barrier to hopping. The nonlinear hopping equations, which exclude jumps to occupied sites, are solved for steady-current conditions in an applied electric field E. The current saturates at a value independent of E and of c for c approximately-less-than eaE/k/sub B/T very-much-less-than 1 where c is the impurity concentration and a the lattice spacing.
