The electrical characteristics of the relaxed isotype n-Si 1 -xGex/n-Si heterojunction are studied for the case of a misfit-dislocation network formed in the vicinity of the heterointerface. The data obtained are used to analyze the energy bands of the heterostructure. The band structure of the crystal near the interface is shown to be formed by a charge at lattice defects. The potential-barrier parameters are estimated by analyzing the temperature dependences of the J-U and C-U characteristics of the system.
