An Emergent Quadruple Phase Ensemble in Doped Bismuth Ferrite Thin Films Through Site and Strain Engineering

Advanced Functional Materials, Volume 34, Issue 39, September 25, 2024.
A morphotropic phase boundary comprising a coexistence of four distinct crystallographic phases is uncovered through A‐site doping and strain engineering. The various ferroelectric, polar, and nonpolar phases form a nanoscale mixture without the presence of crystallographically hard boundaries.
