Understanding Strain‐Induced Phase Transformations in BiFeO3 Thin Films

Experiments demonstrate that under large epitaxial strain a coexisting striped phase emerges in BiFeO3 thin films, which comprises a tetragonal-like (T') and an intermediate S' polymorph. It exhibits a relatively large piezoelectric response when switching between the coexisting phase and a uniform T' phase. This strain-induced phase transformation is investigated through a synergistic combinat...

Finite Element Modelling and Simulation of Phase Transformations in Shape Memory Alloy Thin Films

A unified variational framework and finite element simulations of phase transformation dynamics in a shape memory alloy thin film are reported in this paper. The computational model is based on an approach, which combines the lattice based kinetics involving the order variables and nonequilibrium thermodynamics. Algorithmic and computational issues are discussed. Numerical results on phase nucl...
