Taking as typical values 10 ohm-cm and 0.0025 cm the formula gives 2000 ohms. Actually the forward current at one volt may be as large as 5 to 10 mA, and the differential resistance is not more than a few hundred ohms. Bray 2 has attempted to account for this discrepancy by assuming that the resistivity decreases with increasing field, and has made tests to observe such an effect. In connection with the development of the semiconductor triode discussed in the preceding letter, 3 the nature of… CONTINUE READING
