Pseudopotential Calculations for Ideal Interfaces

  • Marvin L. Cohen
Part of the Materials Science Research book series (MSR, volume 14)


Real interfaces are complicated. Even for a surface resulting from a crystal cleaved in vacuum, it is difficult to eliminate steps, vacancies, and dislocations. If an ideal surface is obtained, reconstruction and charge redistribution are common properties. For solid-solid interfaces, diffusion, misfit dislocations, and other “nonideal” phenomena are common. However, it is still important to understand the ideal cases. A good description of an ideal interface provides a basis for comparison with real systems and allows an identification of observed properties in terms of deviations from ideal behavior.
