Abstract: | Study of the Hall effect on silver films prepared by chemical reduction shows an electronic conductivity. At 25°C the Hall coefficient RH is ?(12 ± 1) × 10?11 m3 C?1 and the number of conduction electrons n = 0.89 electrons per atom agrees within 10% of the result obtained from measurement of the conductivity.The mobility of the electron transport in the annealed films, μHr(25°C) = 4.85 × 10?3 m2V?1s?1 is six to seven time greater than that of the same unannealed films, μHi(25°C) = 0.75 × 10?3 m2 V?1 s?1. |
