The recent discoveries of both chemical-driven and strain-driven morphotropic phase boundaries (MPBs) in BiFeO3 (BFO) thin films have opened up new horizons in developing high-performance lead-free piezoelectrics. An attempt to bridge these two MPBs is made by doping La into highly strained BFO thin...
