Out‐of‐Plane Strain‐Decoupled Architecture for High‐Fill‐Factor Stretchable OLED Displays
Advanced Functional Materials, EarlyView.A vertically decoupled multilayer SOLED architecture separates emissive pixel islands from deformable interconnects, allowing low‐modulus elastomeric layers to accommodate applied strain and suppress strain transfer to the OLED region. This design, combined with transparent hybrid encapsulation, enables a high fill factor (∼75%), stretchability ...

Theory of transition temperature of magnetic double perovskites [PDF]
Physical Review B, 2001 We formulate a theory of double perovskite coumpounds such as Sr$_2$FeReO$_6$ and Sr$_2$FeMoO$_6$ which have attracted recent attention for their possible uses as spin valves and sources of spin polarized electrons. We solve the theory in the dynamical mean field approximation to find the magnetic transition temperature $T_c$.

Advanced Functional Materials, EarlyView.We demonstrate that halide composition determines phase morphology, governing distinct operating mechanisms in mixed halide perovskites. Phase segregating 75% Br compositions enhance solar cell performance, whereas intrinsically phase‐separated 95% Br compositions provide stable light emitting diodes.

Electronic structure of ordered double perovskite Ba2CoWO6 [PDF]
AIP Conference Proceedings, 2014 Ba2CoWO6 (BCoW) has been synthesized in polycrystalline form by solid state reaction at 1200C. Structural characterization of the compound was done through X-ray diffraction (XRD) followed by Rietveld analysis of the XRD pattern. The crystal structure is cubic, space group Fm-3m (No 225) with the lattice parameter, a=8.210A.
