Theoretical and experimental investigations of the conductivity of elastically bent intrinsic Ge are performed. An high asymmetry of the current—voltage characteristic is predicted and observed in plates with a high velocity of surface recombination. It is connected with the deviation of the spatial distribution of carriers for two opposite directions of current, flowing through the crystal. It is shown that a negative differential resistance in thin crystals may arise at great electrical fields. Current oscillations connected with the Joule heating of the specimen are observed.
