A germanium diode is used to detect radiation with energy of 1.6 MeV. To do so,
the anode (positive terminal) is exposed to the incoming radiation. Assume that the
energy is absorbed entirely at the point of entry or the anode. With mobilities of 1,150
cm?/V.s for holes and 3,750 cm?/V.s for electrons, calculate the current through the
diode with reverse bias: V = 24 V and d = 12 mm. Neglect the effects of electrodes and

of the n and p layers and assume a single radiation event, that is a single particle or a
short burst of radiation. (Charge of an electron = 1.602 x 10-19 C; d is the distance
between anode and cathode).
You measure the initial mass of the cathode to be
25.05 ± 0.10 g, and the final mass to be 24.12 ±0.05g.
If a current of 0.45±0.05A flowed for 100±0.5 min,
