Abstract

Perturbed angular correlation measurements were performed after 111In implantation into CuO and Cu2O powder samples and 1 μm thick Cu2O surface layers. The quadrupole hyperfine interaction of 111Cd was studied in isochronal annealing cycles at 370–1170 K covering the CuO→Cu2O phase transition. The electric field gradients obtained for 111Cd on substitutional Cu lattice sites were associated with the repective oxygen coordinations. Annealing of Cu2O surface layers on copper foils resulted in a texture with the efg pointing preferentially out of the surface plane.
