Beyond Entropy: Leveraging Intrinsic Electronic Character to Induce Internal p-n Domains in Multication Perovskite Semiconductors.

Medium-entropy perovskites containing Sn, Zr, Hf, and Te were synthesized via hydrothermal methods. Solid-state NMR confirms a uniform elemental distribution. In these vacancy-ordered double perovskites, the electronic behavior is shaped by more than…
