Design of lead-free antiferroelectric (1 − X)NaNbO₃−xSrSnO₃ compositions guided by first-principles calculations

Antiferroelectric materials exhibit a unique electric-field-induced phase transition, which enables their use in energy storage, electrocaloric cooling, and nonvolatile memory applications. However, in many prototype antiferroelectrics this transition is irreversible, which prevents their implementation. In this work, we demonstrate a general...
