摘要

Nanocrystalline CeO film in the Al/nc-CeO/Si-Al structures has been obtained using flash evaporation method and method of metallic Ce oxidation. The electrophysical properties of the Al/nc-CeO/Si/Al structures and the effect of technological factors on these properties have been investigated. It was revealed that the nanocrystalline CeO layer in the Al/nc-CeO/Si/Al structures is a semiconductor with an electronic conductivity and volume resistivity is within the range of 0.5-30 MΩ·cm. Based on the synthesized Al/nc-CeO/Si/Al structures the new types of heterojunction diodes with high interface quality have been developed. Interface state density of obtained structures is of about 7·10 cm·eV.
