AbstractWe have calculated the work of adhesion (i.e. energy for rigid fracture) and peak interfacial stress for NiAl, Cr, and NiAl–Cr using self-consistent density functional calculations to obtain the complete energy vs. separation curve for each system. Our calculations indicate that the work of adhesion is largest for Cr and smallest for NiAI while those for interfaces of NiAI with Cr are intermediate. We have also estimated that segregation processes could alter the work of adhesion for the AlNi/Cr interface by up to 20% since Al tends to segregate to the free NiAl surface while Ni tends to segregate to the AlNi/Cr interface.

ABSTRACTWe perform self-consistent density functional calculations on semiconductor heterojunctions, using ab initio nonlocal pseudopotentials, and derive valence band discontinuities for many different lattice matched interfaces. Spin-orbit effects are included a posteriori. A comparison is made with previous calculations, which used empirical pseudopotentials, and with other heterojunction theories. We find reasonable agreement with reported experimental values, and derive some important conclusions about the nature of the lineups.
