Ferroelectric and antiferroelectric instabilities in BaTiO3/BaO
... to a Ba-Ba distance of 3.86 Å. Therefore, when grown on a SrTiO3 substrate, assuming a theoretical cubic inplane lattice constant of 3.84 Å, BaTiO3 is under compressive strain and becomes tetragonal, as well as BaO (the epitaxial strain being applied on the Ba-Ba distance) in a smaller extent.26 Aft ...

Quantum reflection and interference of matter waves from
... This is due to the fact that quantum reflection occurs far away from the surface where the influence of the closed-order wave functions is negligible (see [2,3,16] as well as Sec. IV). The generalization of the coupled-channel equations (6) to a potential V (r) which is periodic also in the z direct ...
