The complex effect of strain on the structure of perovskite vanadates

Scilight from AIP Publishing is talking about a recent publication of Hugo Meley and coworkers in APL Materials.

Moving from discovering physical properties to the ability to tailor them requires precise understanding and mastery of materials fabrication. This study unveils how the substrate affects the growth of crystalline vanadate thin films and the arrangement of their atomic distortions. Squeezing the film, by imposing compressive strain with the substrate, suppresses the structural transition that in the bulk manifests the formation of orbital order,  while pulling on the film (tensile strain) recovers its natural behaviour. Can this development of material control lead to creation of an artificial ferroelectric state in layered heterostructures?

Scilight summarizes new and important physics research and emphasizing the significance of a contribution to a field of science.
