Insights into Crystal Structure and Diffusion of Biphasic NaZnTeO.

The layered oxide NaZnTeO is a fast Na ion conductor and a suitable candidate for application as a solid-state electrolyte. We present a detailed study on how synthesis temperature and Na-content affect the crystal structure and thus the Na ion conductivity of NaZnTeO. Furthermore, we report for the first time an O'3-type phase for NaZnTeO.
