Structure of fast ion conducting and semiconducting glassy chalcogenide alloys

Research output: Contribution to journalArticlepeer-review


The method of isotopic substitution in neutron diffraction is used to measure the metal-metal partial structure factor SMM(k) for the glassy fast ion conductor g-Ag2As3Se4 and for the glassy semiconductor g-Cu2As3Se4. The remaining partial structure factors are hence separated into two functions which comprise either the M-μ (μ=As or Se) or μ-μ species. It is found that the short range order of the network former g-AsSe is not destroying on alloying with M2Se and that the most significant structural differences occur with respect to the M atom ordering.
