Abstract

We have determined a unique model for the mobile copper ion disorder in hexagonal Cu2S between 120° and 325°C via single crystal neutron diffraction. The copper ions partially occupy two sets of three-coordinated sites within the HCP sulfur array and display anharmonic thermal motion. The results suggest that the conductivity is two dimensional in nature.
