The room temperature Hall electron mobility of phosphorous doped {111} homoepitaxial diamond is investigated experimentally and described theoretically for different doping and compensating center densities. The impurities mobility dependence is established. The mobility is found to be controlled by the lattice scattering mechanisms in low doped material (below 10(17) cm(-3)), by lattice and ionized impurity scattering for moderate doping level (10(17) cm(-3)< N(D)< 10(18) cm(-3)), and by neutral impurity scattering for highly doped material (above 10(18) cm(-3)). The mobility parameters required to simulate the electric characteristics of electronic devices between 300 and 500 K in a wide doping range are then determined.
