As-cast amorphous AsSe (a-AsSe) has been characterized by in-situ
XRD and Raman spectroscopy up to the pressure of ∼30 GPa using diamond anvil cell together with ab-initio
molecular dynamics simulations. A gradual densification has been observed under compression along with the breakdown of intermediate range ordering at ∼16 GPa. The whole transformation process can be divided into three relatively distinct pressure regimes from 1 bar to 7 GPa, from 7 to 16 GPa, and beyond 16 GPa. Our XRD results together with Raman spectroscopic studies confirm that in the a-AsSe pressure tuning results in network transformations only, without sudden jump in the density. The results obtained by high pressure
molecular dynamics simulations demonstrate the variations in the local structures associated with the experimentally observed transformations. The amorphous-to-amorphous network transformation is found to be reversible upon decompression.
