Short-Range Structure in Amorphous Ge3(Se1—xSx)4 and Ge3(Se1—xTex)4 Alloys

The short-range structure in amorphous Ge 3 (Se 1-x S x ) 4 alloys with = 0 to 1, and Ge 3 (Se 1-x Te x ) 4 alloys with =0 to 0.25 has been investigated through X-ray diffraction and Raman scattering measurements. Raman spectra in both amorphous alloys have revealed that structural units containing a direct Ge-Ge bond, such as X 3/2 Ge-(GeX 2/2 ) n -GeX 3/2 or Ge(Ge (4-m)/4 X m/2 ), are formed in the alloy, in addition to the remaining GeX 4/2 tetrahedral units (X = Se, S and Te). The structural analysis by the X-ray diffraction method has indicated that the bonding distances of Ge-S, Ge-Se, Ge-Te and Ge-Ge pairs, which are involved in the first coordination shell, are all composition-independent and very close to the correponding covalent values, and the coordination numbers of the constituting atoms are nearly four for Ge and two for X. Any indication on a direct X-X bond has not been observed in the present measurements, which suggests that every X atom in the alloy preferentially coordinates to Ge atoms. The local order corresponding to crystalline GeX has not been found out in both amorphous alloys.
