• The temperature-dependence of rectifying action of silicon and iron pyrite detectors was measured between -183℃ and 300℃. The maximum rectification ratio for Si-W detector occurs at about 60℃, while for some iron pyrites a kink appears at about -60℃ in the rectification-ratio versus temperature curves, although we have no maximum in the measured range of temperatures. Mott's and Davydov's theories on the reetification are insufficient o explain these results. The author proposes a theory based on the tunnel effect of electrons through the upper part of a blocking layer. in which the calculation was made for the thickness 20Å〜30Å of the blocking layer. It is expected from our theory that there exists a critical temperature at which the inversion of rectification occurs and that the rectifylng action is a function of the thickness of layer and the conductivity of the crystal in bulk, The inversion of rectification at different places on the surface of the crystal can also qualitatively be explained by our theory.
