Mater. Dissociation of super-dislocations and the stacking fault energy in TiAl based alloys with Nb-doping. In order to maintain the strain state of the film even after removing the external stress from membranes, the adhesive polycaprolactone was used in its melted liquid form to bond the stretched membrane onto a rigid substrate at 110C, and then cooled to room temperature to lock-in the strain state (see Methods). In order to investigate the nature of temperature-driven phase transitions in strained SrTiO3 membranes, we first equilibrated the slab model by running NVT (constant-volume constant-temperature) simulation using a time-step of 1fs with a 2.0% tensile strain along the [100] direction.

But given the experimental strain geometry where the membrane elongates along only one in-plane direction while compresses along the out-of-plane direction due to the Poisson effect (we keep the membrane undeformed along the other orthogonal in-plane direction), the possibility of the tetragonal 4mm point group symmetry is thus ruled out from our analysis.

ADS For the experimentally observed 180 ferroelectric domains, we can simplify the problem with the consideration of only one polarization component along the uniaxial strain direction, i.e., P10, P2=P3=0. In this model, we used the power-series expansion of the Helmholtz free energy F in terms of polarization components Pi and structural order parameters Qi (i=1, 2, 3), which is expressed as follows38: where Sn (n=1, 2, 3, 4, 5, 6) are lattice strains, cnl are the elastic stiffnesses, gnl are the electrostrictive constants, nl are the linear-quadratic coupling coefficients between the strain and structural order parameters, and tnl are the coupling coefficients between the polarization and structural order parameters.
