摘要
First-principles calculations based on ddensity-functional theory are powerful tools to investigate the structure and properties of ceramic interfaces. The Schottky-barrier heights of SiC/metal and Al2O 3/metal interfaces have been examined, and significant effects of the interface stoichiometry (termination species) and metallic species have been found. Ab initio tensile tests have been applied to Al2O 3/CU and Al2O3/Ni interfaces, where the strength and features of failure also greatly depend on the interface stoichiometry and metallic species.
