A neutron diffraction study of the structure of evaporated amorphous germanium

Abstract Neutron diffraction techniques have been employed to obtain an accurate, high resolution correlation function for evaporated amorphous Ge. The structure of amorphous Ge is unlike that of any of the related crystalline polymorphs, but is much more accurately described in terms of a tetrahedrally bonded random network. The best fitting random network models, however, all predict too much structure in the correlation function at high r and severa; exhibit too narrow a distribution of bond angles.
