摘要：
We measured the electrical conductivity of 1-2 mum thick n-type intentionally and unintentionally doped gallium nitride samples from 1.5 to 290 K. Room-temperature Hall measurements show carrier densities in the range of 6.6 x 10(16) to 3.7 x 10(18) cm(-3), and mobility values from 543 to 261 cm(2)/V-sec over this carrier density range. Hopping is among impurity sites, and the hopping distance increases with decreasing doping concentration for the silicon-doped samples.
