5.1 An n-type Ge sample is usually used in the schottky experiment. The length of the sample is 1 cm and the probes A and B are separated by 0.95 cm. The battery voltage is E, = 2V . A pulse arrived at point B at about 0.25 ms after injection at point A. The width of the pulse is At = 117µs . Calculate (i) (ii) the hole mobility, and the diffusion coefficient.
