dc.description.abstractElectron transport in gallium phosphide epilayers and indium gallium phosphide epilayers lattice matched to GaAs has been studied. The epilayers were grown using LPE with a graphite slider boat in a palladium diffused hydrogen atmosphere. The gallium phosphide electron v-E characteristic was measured using a novel variation on the conductivity technique. The resulting curves were fit using a nonlinear least squares method to two empirical models commonly used for silicon. The resulting drift mobility, ~ 85 cm^2/v - s, is half the measured Hall mobility. The resulting saturated drift velocity, ~ 1.3 x 10^7 cm/sec, is consistent with predictions and is substantially higher than for narrower bandgap III-V compounds. In addition the electron Hall mobility has been measured in indium gallium phosphide layers lattice matched to gallium arsenide. The resulting Hall mobilities, ~ 1000 cm^2/v - s, are approximately an order of magnitude greater than for gallium phosphide.en
