Abstract
The structure of nanoscale void-species has been studied in glassy arsenic selenide g-As2Se3 by combining the first sharp diffraction peak in X-ray diffraction (FSDP-related XRD), treated within Elliott’s void-based model, and positron annihilation lifetime spectroscopy (PALS) within two-state positron trapping model. By suggesting that the same nanovoids are responsible for both FSDP and PALS data, the analytical correlation relationship between the FSDP position, Q1, and nanovoid diameter, D, has been presented in the form of Q1 = 2.3 · π/D.
