Neutron diffraction study on the medium and short-range order of ternary chalcogenide glasses.
Original language description
Glasses from Ge.sub.x./sub.As.sub.40-x./sub.Se.sub.60./sub., Ge.sub.x./sub.Sb.sub.40-x./sub.S.sub.60./sub. and Ge.sub.x./sub.Sb.sub40-x./sub.Se.sub.60./sub. families have been investigated by neutron diffraction. The well expressed 'first sharp diffraction peak' of the neutron spectra at Q= 10- 14 nm.sub.-1./sub. has been explained by a pseudo-binary model of the structure of studied chalcogenide glasses. The amplitude of this interference maximum increases with Ge-content in all investigated samples. Experimental radial distribution functions show that the basic structural units, GeS(Se).sub.4./sub. tetrahedra and As(Sb)S.sub.3./sub. or As(Sb)Se.sub.3./sub. pyramids persist in glassy state for the whole range of studied compositions. Crystal-like model distribution functions have been used to describe the short-range order observed. A shortening of heteropolar bonds in S-containing glasses as well as an increase of heteropolar bonds length in Se-containing glasses has been found.
