Abstract

The structures of bulk amorphous Zn41Sb59 and of GaSb alloys, produced by solid state transformation of the high pressure crystalline phase, were studied by neutron diffraction. The results are compared with the structure of crystalline compounds of the same composition. The structure of the amorphous GaSb is interpreted in terms of a distorted network of ZnS blende type. The local atomic coordination in the ZnSb alloy is basically tetrahedral but the tetrahedra are deformed and interlinked. A comparison with the structure of other amorphous semiconducting materials with tetrahedral bonding is also presented.
