Задача id17099

The resistivity of pure germanium at 27 °C is 0.47 Ohm-m, silicon - 2.3 103 Ohm-m. Using the data from § 45.1, determine the concentration of electrons and holes of these semiconductors at a given temperature. Compare with the concentration of conduction electrons in metals (see Vol. 1, § 44.2, Table 44.1).
