Research Abstract

Interfaces between metal electrodes and oxides used for electronics applications such as insulating films for next-generation LSIs and transparent conducting oxide films for solar cells, are one of the crucial factors that determine the performance of devices. Such oxides are composed of oxygen O and metal element A. At the interface between oxide AO and metal B, two types of interface bonding, A-O-B and O-A-B are possible. In this study, it has been revealed that the electric property of a device is completely difference due to the difference in the type of interface bonding at one atomic layer thickness. Furthermore, a method to predict thermally stable interface bonding at different oxides and metals are proposed.
