Consider a p-type Si sample with a resistivity of 0.5 · cm. The doping level is uniform throughout. In a certain portion of this sample, there is an electric field of a magnitude 1000 V/cm. Estimate the magnitude of:
a) the electron drift velocity,
b) the hole drift velocity,
c) the electron drift current density,
d) the hole drift current density,
e) the total drift current density.
