Task id17100

Using the data from the previous problem, determine the Hall constant in these semiconductors. 31.15. 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).
