Spin instabilities in semiconductor superlattices
The subband levels of quantum wells grown in a periodic array form minibands whose bandwidth D depends on the probability of interlayer tunneling. In the presence of a strong magnetic field, this system of minibands can exhibit various Coulomb-interaction-driven spin polarization instabilities at an integral value of the filling factor n . We investigate in particular the Hartree-Fock phase dia...
متن کاملPiezoelectricity in the dielectric component of nanoscale dielectric-ferroelectric superlattices.
The origin of the functional properties of complex oxide superlattices can be resolved using time-resolved synchrotron x-ray diffraction into contributions from the component layers making up the repeating unit. The CaTiO3 layers of a CaTiO3/BaTiO3 superlattice have a piezoelectric response to an applied electric field, consistent with a large continuous polarization throughout the superlattice...
متن کاملPerovskite oxide superlattices: Magnetotransport and magnetic properties.
We have fabricated perovskite superlattices consisting of two ferromagnetic metallic oxides: La0.67Ca0.33MnO3 ~LCMO! and SrRuO3 ~SRO!. We have investigated the magnetotransport and magnetic properties of a series of samples, in which the layer thickness of LCMO is fixed and that of SRO varied from 0 to 20 unit cells. The magnetoresistance ratio in a superlattice can be increased by a factor of ...
متن کاملCompeting structural instabilities in cubic perovskites.
We study the antiferrodistortive instability and its interaction with ferroelectricity in cubic perovskite compounds. Our first-principles calculations show that coexistence of both instabilities is very common. We develop a firstprinciples scheme to study the thermodynamics of these compounds when both instabilities are present, and apply it to SrTiO3. We find that increased pressure enhances ...
متن کاملWannier-based definition of layer polarizations in perovskite superlattices.
In insulators, the method of Marzari and Vanderbilt [Phys. Rev. B 56, 12 847 (1997)] can be used to generate maximally localized Wannier functions whose centers are related to the electronic polarization. In the case of layered insulators, this approach can be adapted to provide a natural definition of the local polarization associated with each layer, based on the locations of the nuclear char...
