Coincidence‐site‐lattice relations for MgO‐CdO interfaces

Abstract

Abstract Electron microscope measurements of the angular distribution of small, cubic MgO and CdO crystals deposited on MgO {100} single‐crystal substrates show marked preferred orientations. The coincidence‐site‐lattice (CSL) theory for CdO/MgO interfaces is given and the measured distribution correlates well with CSL theory. The observed orientations are thought to be produced by the coherent rotation of the small crystals to orientations that have a local minimum in the interface energy.
