Electrical conductivity of a cleaved (111) face of germanium
Aristov V. Yu., Tal'yanskii V. I., Kharlamov A. A.
The electrical conductivity of the germanium (111) face formed by cleavage at liquid-helium temperature in high vacuum increases sharply and irreversibly after heating to Τ ~Ί0 К. The temperature at which this irreversible increase occurs is strongly dependent on the medium in contact with the crystal. It is suggested that the observed effect results from an irreversible restructuring of the (111) face.
