Problem 2 (10 points) For a 1 cm intrinsic Germanium crystal, at liquid nitrogen temperature (77K) the intrinsic carrier concentration is 10/cm3. At this temperature the electron and hole mobilities are the equal, μ.-An-36192 cm 2/Vs. If 100 V is applied across the Ge cube at 77K, what is the current you measure?5 pt a) b) If uah4.9-107-T-166 (cm2V1s1), what is the current at 300K?5 pt

**Please Show All The Steps**
As I mentioned in the class assume that we have a GaAs (Gallium
Arsenide) sample which was doped with excessive As to produce a
resistivity of 0.05 Ωm. Owing to the presence of an unknown
acceptor impurity the actual resistivity was 0.06Ωm, the sample
remaining n-type. What were the concentrations of donors and
acceptors present?
(Please take μe=0.85 m2/Vs and assume that all impurity atoms
are ionized)
