| Abstract: | An analysis of the atomic radial distribution function of Al0.20As0.30Te0.30, Al0.10As0.40Te0.50 and Al0.10As0.20Te0.70 amorphous alloys obtained from quenching of the molten mixture of the elements was performed. A structure in which all the Al atoms are tetrahedrally bonded to the other types of atoms in the material, would satisfy the requirements of the experimental curve. Tetrahedral groups might be linked to each other by As and Te atoms, or directly through a Te or As atom belonging to more than one tetrahedra. |
