Strain-induced isosymmetric phase transition in BiFeO3
We calculate the effect of epitaxial strain on the structure and properties of multiferroic bismuth ferrite, BiFeO3, using first-principles density-functional theory. We investigate epitaxial strain corresponding to an 001 -oriented substrate and find that, while small strain causes only quantitative changes in behavior from the bulk material, compressive strains of greater than 4% induce an is...
متن کاملPhase transition induced strain in ZnO under high pressure
Under high pressure, the phase transition mechanism and mechanical property of material are supposed to be largely associated with the transformation induced elastic strain. However, the experimental evidences for such strain are scanty. The elastic and plastic properties of ZnO, a leading material for applications in chemical sensor, catalyst, and optical thin coatings, were determined using i...

متن کاملStrain-induced phase transition of a C58 solid.
Four kinds of C58-based carbon solids and some of their physical properties are predicted by the first principles calculations. These carbon solids display different electronic structures, due to their different space symmetries and connecting patterns. Among these solids, the most stable one with the P3m1 space group displays semiconducting properties, with a direct band gap of about 0.12 eV, ...
