Abstract
The drift mobility of nonequilibrium holes injected in undoped polycrystall ine diamond films was determined, by a transit-time technique, as ca. 10(-3 ) cm(2)/(V s). This hole mobility is three orders of magnitude lower than t he "equilibrium" mobility in boron-doped diamond films [0.1-1 cm(2)/(V s)], determined from the films' de conductivity. This difference is explained b y the effect of a nonequilibrium charge carrier trapping during the carrier transport in polycrystalline diamond.
