Why does the hole concentration reduce when pentavalent doping is increased?

In a 10 - μm long bar of donor-doped silicon, what donor concentration is needed to realize a current density of 1 mA / μm^2 in response to an applied voltage of 1 V. (Note: Although the carrier mobilities change with doping concentration, as a first approximation you may assume μn to be constant and use the value for intrinsic silicon, .1350 cm^2 / V ·s). | Numerade
