Crystallographic Parity and Inverse Area Scaling in Two-Dimensional Perovskite Ferroelectric Tunnel Junctions.
Ferroelectric tunnel junctions (FTJs) are promising for next-generation high-density non-volatile memory; however, conventional polycrystalline oxide FTJs face issues with defect-induced leakage and degraded ferroelectricity at nanometer scales. Here, we demonstrate atomically defined nanocrossbar FTJs based on single-...
