摘要:
The electrical conductivity of germanium deposited at 80 K has been found to vary with temperature with a small activation energy. On annealing, the characteristics follow more closely the familiar T−1/4law, derived for variable‐range hopping at the Fermi level. The conductivity of all samples increases with electric field above a threshold value. The optical absorption edge sharpens on annealing. Various models to explain the data are considered.
