There is a p-type semiconductor box. As the voltage at both ends of the box continued to increase, the drift velocity of the holes in the box reached the saturation velocity. After that, if the acceptor doping concentration in this semiconductor box is doubled and the voltage is also doubled, how will the current change in this semiconductor box change? However, it is assumed that the mobility is affected only by impurity scattering. .
