Selective optical excitation of a substrate lattice can drive phase changes across heterointerfaces. This phenomenon is a nonequilibrium analogue of static strain control in heterostructures and may lead to new applications in optically controlled phase change devices. Here, we m ...
Nucleation processes of mixed-phase states are an intrinsic characteristic of first-order phase transitions, typically related to local symmetry breaking. Direct observation of emerging mixed-phase regions in materials showing a first-order metal-insulator transition (MIT) offers ...
Static strain in complex oxide heterostructures(1,2) has been extensively used to engineer electronic and magnetic properties at equilibrium(3). In the same spirit, deformations of the crystal lattice with light may be used to achieve functional control across heterointerfaces dy ...
