Current-voltage relations in bismuth orthogermanate crystals with Ag, Pt, InGa
electrodes have been measured in the modes of double and unipolar injection of
charge carriers. It has been shown that Bi₄Ge₃O₁₂ is relaxation type semiconductor. The
appearance of the regions with negative differential resistance or sublinear rise of the
current in characteristics is connected with the injection of the minority charge
carriers and recombination processes in the space charge layer.
