Consider a n-type silicon sample. If a power supply is connected between two ends of the silicon sample with 5 volts of voltage, 5 milliampers of current
flows through the sample. If Na=3x1014 cm-3, N3=0, Dn=10 cm2/sec, Dp=20 cm2/sec, kt/q=D0.025 volts, obtain mobilkity if the sample area is two times
its length in magnitude. (q=1.6x10-19 C, T=300 °K, kT=0.025 Ev, n=1010 cm-3)
