Several metals with strong ionization tendency were found to form rectifying contacts with chalcogenide amorphous films. Measurements of frequency dependences of parallel capacitance and resistance of sandwich-type samples of Metal (I) / amorphous film / Metal(II) revealed that rectifying effects were due to the formation of a high resistivity layer with large thickness, which was thought to be caused by a chemical reaction at the interface.
