Mobilities change with doping concentration

Reference no: EM131019889

In a 10-μm-long bar of donor-doped silicon, what donor concentration is needed to realize a current density of 2 mA/μm2 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 1350 cm2/V · s, the value for intrinsic silicon.)
