Polarity identification of some AB compounds of tetrahedral coordination

Abstract
The basic principles of a possible polarity standard for non-centrosymmetrical materials of adamantine structure are discussed. In view of the obvious lack of a standard convention for the designation of polar planes for these materials, placement of the “metal” A atom in 000 position, and a positive value of the displacement parameter fixing the “non-metal” partial B lattice are suggested for a general standard. The absolute polarity has been determined for InP, GaP, GaSb, AlSb, and ZnSe and related to specific etch patterns. Etch-pit microphotographs of the major polar planes of these materials, and their respective light figures are given and discussed.
