A complete substitutional solid solution, Bi3.08Cu1.84−xZnxTa3.08O14.16: 0 ≤ x ≤ 1.84, was prepared by solid-state reaction at temperature 950°C over 48 h. These thermally stable pyrochlores exhibited a remarkable transition from semiconducting to highly insulating behavior as their electrical condu...
